A Winter Hike at Mt. Pleasant (1)

/

Last week I hiked at Howard Country Conservancy’s Mt. Pleasant on a sunny, cold morning with snow still on the ground in many places. The group I was with started out beside the Community Garden then then took the path toward Hodge Podge Lodge. Since I was with a group….I only had time for short stops for photography.

I stopped on the bridge just after Hodge Podge Lodge to take some pictures of ice crystals at the edge of the frozen stream.

A little further along – it seemed like there was more snow on the ground and I turned back to photograph Hodge Podge Lodge on the other side of the stream and through the trees.

One of the plants I always look for this time of year is skunk cabbage. They were not as visible as in most recent mid-Februarys because we’ve been having some colder days recently. There were a visible and I’m sure there were more if I’d had time to look more thoroughly. I’ll go again to spend more time…try to photograph one that is blooming.  

It’s easy to see irregularities in bark and hollows in the winter. I wondered if this tree was still alive…will remember look in the spring to see if it turns green with the rest of the forest.

There were several logs with turkey tail (shelf fungus) on them…and there was snow caught in the turkey tails.

Someone had left a handprint (no thumb) in the snow on one of the trailside benches.

We hiked to the champion Tulip Poplar at the edge of the Mt. Pleasant property. There is a housing development happening on the other side of the property line that may be problematic for the tree.

I took pictures of the bark – lots of holes and old wounds – and a large hollow (evidently black vultures have been seen entering/leaving the hole!).

I’ll post more tomorrow with  macro photography I did after the hike – back at the nature center.

Frost on the Recycle Bin

/

Last week when I went out to retrieve our recycle bin (the truck comes around 6:30 AM!), I noticed that frost has accumulated on the black lid. It didn’t look too promising….just a thin film of frost. But with a magnifier it was much more interesting! I already had my phone with me; the clip-on magnifying lens and clicker were in the pocket of the fleece vest I was wearing. I took advantage of the outdoor light before I pushed the bin into the garage.

It was close to the time the middle school bus was due in the neighborhood and a boy was waiting for it – apparently listening to music through earbuds. I smiled at him but didn’t interrupt his morning. He probably wondered why I was so interested in the top of the recycle bin!

It felt good starting the day noticing something…. photographing it… catching the serendipity of icy crystals before they melted.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The subtle influence of the moon on Earth’s weather – Tides….and a lot of complex interactions associated with them. High tide flooding will increase as the climate changes for example.

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Top 25 Birds of the Week: Seedeaters! – Starting out the gleanings list with bird photographs.

Mapping tree inequality: Why many people don’t benefit from tree cover – Trees are an effective way to reduce the heat island effect within cities (i.e. where there are fewer trees it is hotter). Lower income communities tend to have fewer trees…and thus are hotter. As there are more hot days, the impact is becoming greater. There is also a beauty to trees…each one is an island of nature in a sea of concrete and asphalt. Increasing trees in cities and towns is an investment in physical and mental health!

Roman temple at Egyptian Emerald Mine – In the eastern Egyptian desert. The researchers found 19 coins, incense burners, bronze and steatite figurines, bones, terracotta body parts, and amulets.

Return of Brood X Cicadas – This brood emerges in the area where I live in Maryland. I am not there to see it, but I hope my husband can photograph some emerging cicadas. There should be lots of opportunities!

Invasive Jumping Worms Have Spread to 15 States – This species is in the middle of the country. I haven’t seen any yet in Texas, but they are in the state and my daughter might have them in Missouri. Hopefully, there will be a method to control them soon or the landscape of that area of the country could change…they are a small organism with a big impact.

A Retreat to Catoctin – This park is close  (about an hour) from where I live in Maryland. I’ve been there many times….maybe not often enough.

Hopes and Weeping Trees: What’s up with the Yellow-bellied Sapsucker? – Neat rows of holes in tree trunks? There is a sapsucker around. Sometimes hummingbirds will come to get the sap dribbling out of the holes. I am always pleased to discover a tree that has been visited by a sapsucker; I noticed when I was at Mt. Pleasant this spring that the tree that was convenient to a hiking route for school field trips (pre-pandemic) has been cut down so I will hunt for another one to share with hikers.

Trove of 2,000-Year-Old Bronze Mirrors Found in Ancient Chinese Cemetery – 80 mirrors….ranging from 3-9 inches in diameter. There are other artifacts recovered from the same cemetery….maybe more stories to come as the excavations and analysis of finds continues.

Charting ice from above – The Icebird flights….flying low over ice and open water. What if feels like to be part of the crew.

National Parks Traveler Checklist: Padre Island National Sea Shore – My husband and I have been to parts of the Padre Island National Sea Shore for snippets of time. Our plan to visit in 2017 to see more of the park was cancelled after Hurricane Harvey…maybe we should add it to our post-pandemic travel plans!

Ice Shelf

/

The skylight in the roof of our cover deck slopes enough that the snow and ice it accumulates acts like a mini-glacier as it melts. Over the past few days, our part of Maryland stayed cold with melting occurring with the sunshine even as the temperature stayed below freezing. And then everything re-froze overnight. The snow was icy and dense rather than fluffy because the majority fell as sleet….and as it began to slide down the slippery slope of the skylight, an ice sheet formed.

Did the icicles that formed at its edge provide any support?

2021 02 IMG_3777 (3).jpg

It lasted for more than 24 hours with the re-freezing overnight although there was a noticeable erosion of the ice closest to the skylight housing during the first exposure to sunshine.

2021 02 IMG_3812.jpg

I watched it all morning the second day as the sun came up and the skylight began to get full sun as the morning progressed. About noon – the shelf cracked (I heard it rather than saw it)…slid down the rest of the roof and gutter and crashed to the deck below….shattering on impact.

It was awesome to watch this small model of glacier and ice shelf behavior --- think about how the process would translate to a larger scale and longer duration in the Antarctic.

3 Days of Snow

/

Today our forecast is mostly cloudy…after three days of cloudy skies and snow. The streets are already clear, and the driveway has some clear patches without us ever shoveling. We enjoyed our snow days but are glad to see a bit more sun!

On the first day we had a lot of webinars from the Space Coast Birding and Wildlife which we were watching on the biggest screen in the house (the television) and had a fire going in the fireplace. We had a power failure a little before 8 AM for a few seconds and the cable/internet was out for about an hour afterward. It’s a good thing the first festival session of the day was recorded so we could watch it later!

I tried some snowflake photography twice during the day. I used my phone with a clip-on lens that included a light and a red glass plate to catch the snowflakes. The temperature was about 30 degrees which is on the warm side for good snowflake photography.

The flakes during the first session about 8AM were clumping although there was one that seems to look like a pyramid with a hexagonal base! Even though I had cooled down the plate and lens for over an hour, there was still some melting.

During the second session shortly after noon, it was easier to see individual snowflakes, but they were heavily encrusted with tiny ice spheres.

I tried to capture some scenes from our back and front yard over the course of the day. Our deck and bird feeder still drew the birds even while it was snowing.

I made snow ice cream in the afternoon – after enough snow had accumulated. We ate the whole big bowl!

20210131_160036.jpg

Overnight there was freezing rain so there was an icy crust on everything the second day.

I cracked the ice of the top of the snow on the deck and made snow ice cream again. It was too icy, but we ate most of it anyway.

It snowed more overnight than we though it would so the third day had snow on top of ice. I worried that it might be too heavy for some of the trees because there was some wind as well….but we didn’t hear or see any breakage.  I took pictures of scenes through several windows.

Two of my favorite pictures of the day were taken through the windows on the side of the front door. The vertical ice and snow covered thread in the azalea is an old spider web that’s been there since last fall! The seed pod with a hat of ice and snow is a black-eyed Susan from last summer.

Our plum tree was so full of snow that it obscured the evergreens across the street. The view through the skylights was different too; one had patches of ice partially obscuring the branches of the sycamore in the background.

As always – the view from my office window was the best in the house.

Are sleep trackers accurate? Here's what researchers currently know – It’s not always good to track sleep….particularly if it causes anxiety. I am in the group that generally has good sleep, so the tracker data doesn’t cause me anxiety, but it probably doesn’t improve anything either!  I might get a much simpler tracker next time that doesn’t provide sleep metrics.

Ice Bubbles

/

Sometimes there is a surprise opportunity for a photo shoot. Last week I was out putting seed in our bird feeder – and noticed that there was ice melting on the green lid of a bucket. Sycamore leaves and tulip poplar seeds had been on the lid before the snow fell… and were trapped in the snow melt that had refrozen overnight. The bubbles and pattern of water/ice were perfect for some quick photography.

I like finding things like this rather than trying to create them although there might be some value to creating some opportunities. Maybe as the cut flowers fade – I’ll experiment with immersing them in water and putting them in the freezer (now that it’s cleared out enough to have the space for this type of experiment) - creating ice bubbles and patterns to photograph.

Ice Day

/

The snow changed to sleet then rain around 3 PM and then the temperature dipped below freezing again overnight leaving it looking like snow on the ground but there was an icy crust on top of the snow and the streets were rutted ice. The gutters of the house were clogged with snow that had become icy. So – we had an Ice Day after a Snow Day.

I took some pictures in the early morning darkness. The temperature was about 25…and it looked like there was still white everywhere…the street looking white too. I’d heard a vehicle go by and there were enough cracking sounds to indicate that the street was not clear…was not turned to slush by an application of salt.

2020 12 IMG_3206 (3).jpg

As the sun came up, the street looked treacherous and our driveway looked snow packed. I took some zoomed pictures of the azalea outside our front door with ice nodules held by its leaves.

2020 12 IMG_3206 (4).jpg
2020 12 IMG_3206 (5).jpg

I had scheduled a donation pickup from our front porch which I changed to leave in the garage – although I’m not sure they will come…maybe the street will be better by this afternoon.

The best picture of the morning was of our backyard. I didn’t realize until I was reviewing the pictures that I’d gotten the shadow of a dove in flight! My intent was to document the low place in our backyard making a little stream of melt water….but sometimes the unexpected happens and makes for more than a documentary picture.

Hummingbirds' rainbow colors come from pancake-shaped structures in their feathers -- ScienceDaily – Hopefully they’ll produce some illustrations for these findings; this article and the materials it came from are just text.

New Discoveries in Human Anatomy | The Scientist Magazine® - It’s surprising the things we are just now discovering about our anatomy. Back in the 1970s when I was getting an undergraduate degree in biology, I remember being disappointed that there was so much obviously missing….and then realizing there were also unknown unknowns (thing we didn’t even know we didn’t know)! In the intervening years more has been researched, but we still have lots to explore.

Processed foods highly correlated with obesity epidemic in the US -- ScienceDaily  - I have kept a food log for the past few years and now am paying more attention to reducing the processed and ultra-processed foods that I buy and eat. Most of us probably intuitively know that the store-bought cookies, chips, snacks, etc. are not what we should be eating. And they aren’t even more convenient than foods like carrots or apple or grapes. I’m skewing my purchases at the grocery store to the produce aisle!

Top 25 Wild Bird Photographs of the Week: Doves and Pigeons - Wild Bird Revolution and Nectarivorous Birds - Wild Bird Revolution – Two groups of bird photos this week…catching up on the backlog.

The 2020 Community Power Scorecard | CleanTechnica – A map of the US and the scorecard with some details – state by state. There is progress being made in the transition to renewable energy!

New, more appealing varieties of kale in the works - UPI.com – I like kale. I buy it in a bunch to avoid plastic bags or containers…use it in smoothies or stir fries or soups (the whole leaf and stem) and as chips. I rarely use it in salads (particularly during the winter when I tend to want something hot rather cold for meals). Chopping it up in the food processor (like in smoothies or before adding it to soups) makes the toughness of the stem and leaves a non-issue. Still – I would try the new varieties. I wonder how long it will be before some of them show up in my CSA share.

Ice Bubbles

/

Last week there were plenty low temperature nights. I started a project to collect frost flowers on a red glass plate to photograph. The conditions were not right for frost a single night! But – it did rain a little and the water that collected froze around the red plate that I had slanted in a container.

20190308_083517.jpg

When I pulled out the plate and the ice, I noticed that there were a lot of bubbles in the ice and modified my plan to photograph them.

I started with the lower magnification (15x) macro clip-on lens for my phone. The bubbles that were near the surface of the ice look fractured – not quite round.

My favorite at the 15x magnification was near the edge of the ice – where it met the plate. There were some long narrow bubbles as if the air was climbing the slope of the plate.

20190308_083506.jpg

I switched to my 60x macro lens with its own light source. The bubbles look jewel-like and the color of the red glass plate come through the ice.

My favorite was one that did not have the red color. It looks like a grayish pearl.

o 20190308_083025.jpg

I am still hoping for some frost flowers and there is a possibility since it’s only March. There should be a few more frosty days for us here in Maryland.

New Study Shows Flood Risks Across the U.S. are Underestimated (in a Big Way) – Cool Green Science – I wonder how long it will be before the FEMA maps are updated. It seems like people purchasing houses would like to be aware of the flood risk before they made their purchase.

HoLLIE – week 3

/

The Week 3 of  HoLLIE (Howard County Legacy Leadership for the Environment) class day was last week and it was held at NASA Goddard like the second week. The theme for the day was continued from last week: “what informed citizens need to know about earth systems science.”

The first talk of the day as about ice sheets and included a discussion of the speakers trek to the South Pole last year. Check out her ICESat-2 Antarctic Traverse Blog (The first post is from December 4, 2017. If you want to start with that one and read in chronological order, scroll down to the bottom of this page until you get to ‘Heading South, to New Zealand and Beyond.’ Then after reading the ‘South Pole Station: The Last Stop Before the Traverse’ beginning at the top of the page, click on ‘newer entries’ to read the rest of the of the posts – and again start with the post at the bottom of the page and work up). She spent Christmas at the South Pole!

She recommended a book that I found could be checked out from Internet Archive when I got home: The two-mile time machine by Richard B. Alley. The book is about the annual rings of ice from cores drilled in Greenland and what they tell us about Earth’s climate over time.

The second talk was about the Land-Based Hydrology Cycle. This talk included what we can learn from satellites but also what measurements are taken on land too (and how much effort that takes…to get even sporadic data). With fresh water being so key to life – the very highs (floods) and very lows (droughts) are major impact all around the world.

The third talk was about the Black Marble project…about what we can learn from looking at the earth at night. Back in April there was good summation of the project – to create the images more frequently so that they could be used more even more applications (like short-term weather forecasting and disaster response): New Night Lights Maps Open Up Possible Real-Time Applications - https://www.nasa.gov/feature/goddard/2017/new-night-lights-maps-open-up-possible-real-time-applications; take a look at the map of India midway through the article and slide the vertical bar to the see how the northern part of the country was electrified between 2012 and 2016. There is more at https://earthobservatory.nasa.gov/Features/NightLights/.

The fourth talk was about how the Montreal Protocol saved the earth’s ozone layer. I knew the protocol concerned Ozone and CFCs….but didn’t realize any more history than that. The timing of a report that linked CFCs to ozone depletion just before the ‘hole’ was discovered in the ozone layer (a major change from measures of ozone for many years beforehand) over Antarctica made for a dramatic beginning to the conversation. It has been effective because governments engaged industry that provided substitutes (some transitional) that made it possible to move away from compounds that were ozone damaging in the stratosphere.

Next we visited NASA’s Scientific Visualization Studio – seeing some of their recent work on a wall sized screen. Here are some web versions of what we saw in the studio:

Icy Crystals on Grass

/

Last week when I took my walk at Howard County Conservancy’s Mt. Pleasant Farm, there were ice crystals all over the grass on the paths. It was early enough in the day that the sun had not been out long enough for the ice to melt completely. The ice was in feathery crystals along the stems.

When I got to the bridge over the little stream near Hodge Podge Lodge, the moving water looked on the verge of freezing; the places that were shallow and slow over rocks has crystallized overnight.

The largest crystals were on some straw near the skunk cabbage. They make the straw ‘fuzzy’ although there are some that look like nodules too.

In one place the ice had melted but there were lots of tracks – deer and human! It must have been wetter when they came through since I did not leave any tracks at all!

HoLLIE – week 2

/

The second HoLLIE (Howard County Legacy Leadership for the Environment) class day was last week and it was held at NASA Goddard. I was worried about hitting rush hour traffic so left very early since we were to meet in the Goddard Visitor Center parking lot to catch the bus into the facility. The day was sunny and clear…but very cold and breezy. I managed to take this picture of the visitor center (not yet open) without getting out of my car!

The theme for the day was “what informed citizens need to know about earth systems science.” It was the first of two days that our classes will be at Goddard; last week we started with lectures on “understanding the tools and the state of the art in earth science” from the Project Scientist for the AQUA satellite and then got a tour of mission control for several earth science satellites from the Aqua Mission Director. They did a good job of demonstrating the types of data that can be collected, the methods used to collect it, and the ways it has been analyzed. I was surprised to see the LRO (Lunar Reconnaissance Orbiter) mission control in the same building. That brought back the memory of my daughter being on the team to do image calibration shortly after it launched during her undergraduate days!

On the way back to our classroom, we stopped by the replica of the big rock found at Goddard that has mammal and dinosaur and mammal tracks. This was not on our agenda originally but was a wonderful serendipity aspect to the day even if it took part of our lunch time. I’d read about it in one of my news feeds and followed the link to the paper…but it was such a thrill to see the exhibit and hear the short lecture. I managed to take a few pictures.

We started the lectures on ‘understanding the science of earth’s cycles’ that will continue in this week’s class. We talked about the oceans and the carbon system in this second class. One of the interesting videos in the lectures is available online: twenty years of global biosphere data mapped on a slowly spinning globe; it easy to see the annual cycles. With the massive amounts of data, visualization becomes an important component.

When I got home an article in one of my newsfeeds talked about climate models that are developing that explain why there might be a linkage between melting of Arctic sea ice (one of the topics for the HoLLIE lectures this week) and droughts in California (How nuclear weapons research revealed new climate threats). It was easier to understand since I had the background of the lectures!
