At first glance, Northerners may mistake this for fine snow blown on a bitter wind; but no, this is indeed a north wind, the temperature is above freezing, the material is beach sand. Keeping the sand in place is a concern for Brevard County.
A gull walked through wind textured beach sand, see here in early morning light. Dawn light on beach sand textured by wind, see here in early morning light.
Golden brown infructescences (seed heads) of Sea Oats grass on stalks growing from dunes, seen here in early morning light, are one element of this plant beneficial to the goal of keeping beach sands in place. Tall stalks and broad leaves catch blowing sand. Deep roots hold the plants in place, shallow root systems hold sand in place to form dunes.
Returning after staying away for COVID-19, we found new plantings of Sea Oats by the county.

Walking mornings along the beach I encounter, one after the other, solitary sandpipers, called Willets. Before encountering this group, I noticed massed Black Skimmers feeding in the surf and, on the beach, a single, tiny (1/8th of an inch) fish that I scooped up and returned to the surf. My surmise is these several days around the full moon, fish were being birthed and swarming to provide a bounty that brough these solitary Willets together.

Use your pinky finger to apprehend the sky dome. Imagine yourself at sea, out of sight of land, on a calm day. Keeping your arm extended, place your pinky-tip on the horizon due east, raise your arm directly overhead. The average sized pinky-tip will have spanned 90 of its lengths. The distance measured from the horizon to directly overhead, the zenith, is 90 degrees of sky dome, about one pinky-width per degree, one-fourth of the entire 360 degrees of sky around your spot on the globe.
The apparent width of the sun disk from earth covers 1/2 degree of sky dome. The disk center point moves 15 degrees per hour (360/24 = 15). Using these facts to estimate time to sunset is relatively straightforward. Estimating time to dawn from the sky is more difficult. This graphic, “Twilight-dawn subcategories,” is a way to grasping what happens. Your position on the earth globe affects the experience. For example, at northern latitudes above 60°34′ summer nights never become darker than civil twilight because the sun’s midpoint never drops lower than 6 degrees below the horizon. Civil twilight lasts all night long summer times in parts of Sweden and Finland.

The date-time stamp on the first photograph of this series is 6:46:23 am, Cocoa Beach sunrise for February 1st was 7:09:40, 00:23:17, 23.283 minutes in decimal notation, later. This duration divided by 60 minutes in an hour and multiplied by the sun’s apparent velocity across the sky (15 degrees per hour) and minus the .25 degree between sun’s center and disk edge, gives the sun’s center as 5.57 degrees below the horizon: this is a photograph of the sky a minute or so after the sun passed civil dawn into civil twilight. I am not more exact because this calculation does not account the deviation of the sun path from due east at this latitude, lengthening civil twilight duration by almost a minute.
Edge of Civil Twilight: dark clouds soon to take light
The following photograph is time-stamped 7:05:06, 4.567 minutes until sunrise, sun center is just below the horizon, setting the dark clouds of the previous photograph fleetingly on fire.
Civil Twilight at the edge of sunrise
Sunrise has passed in the following photographs, obscured by clouds and making for a great light show. Enjoy!!

Even on vacation I rise early to better enjoy the day. This year’s escape from the Ithaca winter, at Cocoa Beach, up at 5 am with a beach chair and oranges in hand I walked in darkness from our beach side resort to the tide high point. My time occupied by sky watching I peeled, and ate, oranges while locating stars through the wind blown clouds. When the barely perceptible dawn light began I packed it up to find Pam, who asked to be awake for sunrise.
This day, we ate breakfast from ready to eat food purchased from the Publix market close by on Atlantic Avenue, and caught up with the news craziness. We had a day at the Kennedy Space Center planned after the sunrise walk.
Here is our view while walking north along the tide line. In the far far distance are the Kennedy Space Center Vehicle Assembly building and a space launch gantry. Follow the shoreline to find the pier.
We walked nowhere near the pier, barely visible, not to mention Sam Shepard park. The pier and park are a day’s walk. We had a few hours free before our “Lunch with an Astronaut” event at Kennedy Space Center.
The highlight of this sunrise walk was this large sandcastle on the beach in front of a condominium, the Hilton is to the left. Lori Wilson Park is out of sight to the left. A great feature of the park, for us since the International Palms were we stayed is next to it to the north, was the park life guards.
So, we approached this sandcastle from the north. It survived the high tide to a new day, obviously it required time and resources to build. The day before was a big beach day. Wednesday was a brilliant, summer-like day for the first of March.
A little closer, the footsteps inside the first moat are interesting.
Pam next to the castle provides scale
Here is the central pyramid. I enjoy the dawn light on the grasses. That is a sea gull feather on the apex.

The destiny of all our human conceits. Impermanence is part of the beauty of sand castles.
When Pam read my post “Black Skimmers Feeding” she asked, “Where is the photo of resting Skimmers?”
To answer her question, I looked through Cocoa Beach photographs and discovered I did NOT capture the Skimmers resting. Instead, here are a related species, the Royal Tern (scientific name: Thalasseus maximus), whose behavior is similar in that it exclusively feeds from the water. There was a wind that morning and these individuals face into it. These birds are, from a human point of view, well behaved, unlike the opportunistic gull.
I searched around the web for identification of this gull without success.
It dines on a dead fish washed up by the surf. In my previous posting I used the word “grifting” to describe gull behavior, again this is from the human point of view. Gulls are notorious for stealing food from unwary beach goers, brazening walking over to unguarded chips (any kind), for instance, grabbing them and flying off. If the chip stash is large, this sets off a nasty feeding frenzy when tens of gulls swoop in and grab.
Here is a series of photographs, demonstrating this behavior.
With grandchildren in the Miami Area and a sister in Daytona Beach, Florida was on my mind this morning and memories of this beautiful experience on Cocoa Beach came to mind. After an eventful day touring the NASA launch control center, Pam and I took an evening walk during the golden hour, me with camera in hand.
Full in expectation of catching the passing scene with lots of shot I set to full size jpeg mode using a Sony Alpha 700 dslr with a DT 18-200mm f3.5-6.3 lens. The light was exceptional, so I did not expect much post production work.
My first impression was of the line of cruise ships heading south from Port Canaveral, the starboard side lit perfectly behind human denizens of the Cocoa Beach shore, in full enjoyment mode. A synergy of the images struck me. I took a few experimental shots then, as we progressed down the beach front this unusual tableau came into view.
Newlyweds on Cocoa Beach give rapt attention to a distant cruise ship, it looks like an elegant child’s toy.
The session proceeded smoothly and professionally, it was a pleasure to watch. I felt no compunction for capturing these private moments on a public beach, the transcendence of the images reflect well on all participants.

Ulumay is the name of the Native American settlement of the Ais people decimated by disease after the arrival of Europeans. The park is a natural lagoon and bird rookery linked with canals created for mosquito control and surrounded by a manmade dike. A trail on the dike provides access to the waterways for the fisherman, birdwatchers, and paddlers.

I left Pam at the entrance, seen below at the words “Ulumay Wildlife”; she had a reasonable concern about alligators. It is quite possible to find a large specimen blocking the one and only trail. “What? Me Worry?” When pursued by an alligator, remember to zig-zag.
