Four years, many tags, and even more written words later, my PhD thesis is DONE! 🎉 #biologging for #shark and #turtle ecology and conservation 🦈🐢🦑🧪 i have had a blast these past years at @exetermarine.bsky.social @uniexecec.bsky.social

Me holding my thesis at the (very busy) desk i occupied for the past 4 years

Today I know I need to post some more cool deep-sea science but am feeling very resistant today. The best I can do is combine the two. A thread.

Happy Winter Solstice!

These photos were taken with a pinhole camera I made from a beer can and left out from Summer to Winter Solstice - a 6 month exposure.

Bottom line = Winter Solstice. Top line = Summer Solstice.

The lines are the Sun moving across the sky w/some reflections. No line = clouds

A pinhole camera photo taken from Summer to Winter Solstice. It's a bit blurry as the aperture was made with a tiny needle and no focus mechanism. There are yellow to green lines across the photo, that's the Sun moving across the sky over the course of a day. The top line is from the Summer Solstice, the bottom line from the Winter Solstice. Cloudy days don't have any lines or broken lines as the Sun was obscured by clouds. There are some trees on the left, right and in the background.

A pinhole camera photo, a 6 month exposure from Summer to Winter solstice. There are trees on the right side and background. A house with two cars in the drive are visible almost in the center of the photo. The lines are made from the Sun moving across the sky with the bottom line being the Winter Solstice and the top line the Summer solstice. On cloudy days the lines are broken or not visible as the sun was obscured by clouds. The lines show some reflections from a tree trunk. The lines are mostly a white color with some hints of blue, green and yellow in places. Some of the colors could be from rain or snow staining the paper I was using.

Many air-breathing marine animals swim about three body diameters below the water’s surface, which reduces wave drag and saves energy during migration. The common pattern has implications for species conservation. In PNAS: www.pnas.org/doi/10.1073/...

-2200 M tags deployed, all by recreational anglers
-1750 tag cards returned
-17 recaptures reported to date, maps below.
-Longest distance: 617 nm in 21 days!

On the tenth day of Christmas my true love sent to me:
10 springtails leaping,
9 dance flies dancing,
8 ants a-milking,
7 wasps a-swimming,
6 flies a-laying,
5 gold beetles!
4 buzzing bees,
3 French worms,
2 turtle bugs,
And a painting of a small flea.

A photograph of a Staedtler 0.05 pigment liner and Posca pens around a sketchbook with colour cartoon illustrations of 10 leaping springtails. The springtails are stylized, bright orange with tiny cute black eyes. They are wearing pink and white tutu's and ballet shoes and are positioned in different leaping ballet poses!

The tuna
That was in

You were probably
Saving for your study

Forgive me

So sweet
And so cold

Hi! I have to admit I am not sure what the sound impact from windfarms is - i don’t know if we have a definite answer yet. It likely highly dependent on where the farm is and what animals are around - but in general lower level, constant noise is less impactful than instant bursts of loud noise…
