Can you count them all? |
I have found myself a new office! Comfy couches and a beach
view, with plugs and wifi and most importantly not too many people around!
However, the wifi can also a little too easily distract me from the reason I
needed a quiet place... This place offers me the perfect place for analysing my
videos. Each day we do trials, we add 6 more videos for me to analyse for my
dissertation. Each video is approximately four and a half minutes long, and include
three predator simulations, and each of these videos take me about 15-20
minutes to analyse. The analysis consists of taking a still image of the
beginning of the video where the long spines are easy to see and counting each
one of them. Some of the urchins are easy with only 30ish long spines, but
others go up to the fifties... This is the easy part of the analysis, because
the next thing I do is slow down the video and skip to a point which is marked
to tell me we’re about to put the shadow on the tank. Usually, the urchins
react to the shadow by wiggling their long spines in an attempt to deter the
alleged predator. The reaction is more of a twitch really, and it is during
that twitch that I need to count how many of the long spines I can see moving.
Sounds easy, right? To a certain extent it is very simple, but when the urchins
decide to wiggle one spine 90 degrees back and forth it is incredibly hard to
keep track which ones I’ve already counted – even with slow down to only 0.125
seconds of video per each second spent watching! I have used pieces of paper,
notebooks, anything with a straight edge really, to “divide” the urchins so
that I’ll only count a little part at a time. And still I am not sure I am
getting the correct count. If only there was a software to record the movements
that would tell me how many moved significantly haha! Even if at the moment I
am a little behind on the analysis, I am confident that I will get through them
all by week 5. That is, at least the ones that are done by then!
Since my last post a lot has happened and yet I feel like it
all has become routine. Every day we carry water, every day the urchins go back
to the reef and new ones are brought back, and every day we eat breakfast,
lunch and dinner. And every day we do more trials. We have had an interesting
last week with what must be “that time of the month” for the urchins causing
them to spawn in the trial tanks. The first event, when 5/6 urchins spawned has
been dubbed “The Urchin Orgie”, and they haven’t really shown signs of slowing
down... At times they spawn on the way up to the boat, sometimes as soon as we
put them into the trial tanks, and at times they wait until we hit record on
the GoPro. The urchin trials have gone from stressing them out to a bunch of
happy endings...
Some healthy board banter. Lionfish for dinner! |
I’ve gone to the mangroves
a few more times as well, and managed a real life timber fall off the roots. I
was walking over the roots at approximately one meter off the ground, though
when I say walking I mean crawling, I really don’t fancy a broken leg... I was
reaching for a root on my right with my hand, and I closed my grip only to find
the root I was aiming for was still a good 10 cm away from my now closed fist.
My head turned to the left, the direction I was now quite actively falling to,
and I landed wrist and chest first on top a root only 50 cm off the ground...
Luckily, my bones are strong (thank you Finnish milk!) and I didn’t break my
wrist, and I only acquired two bruises; one on the wrist and one on the
breast... literally! After a few minutes of being a little disoriented lying on
my back on some comfy mangrove roots with my legs up in the air, trying to fend
off the dizziness that followed the fall (no worries, I didn’t hit my head), I
insisted we finish the transect we were there to do. I felt fine and was back
in the Groovy Mangroovie mood in no time! Until we got back to the beach, only
to wait for our taxi home for an extra two hours... But there’s no need to go into
detail about how our lunch entertainment entailed listening to two drunk locals
for an hour and a half, while our only phone was dead and we had no means of
trying to contact base to find out where our taxi might possibly be. We got
home in the end!
Millie and Andrew, enjoying a bitta pool time :) |
It is now only two and a half weeks until I go home (time
has passed so fast!!) and we are only four days from having the original amount
of trials done! Four working days, that is ;) Usually the week here ends on a
Monday with Tuesday being a day off, dedicated to laundry, going to town for
snack shopping, and all round lounging around. There is often a Disney film
running on the TV via someones’s laptop, or a marathon of The Big Bang Theory.
As much as I have tried to do my videos on Tuesdays, I frequently find myself
giggling to Sheldon Cooper’s social awkwardness while the urchin on my screen
desperately tries to swat away an invisible enemy.
I’m going to get onto the Lionfish Team’s secret files for
my next post, to reveal all their secrets! So stay tuned! I also need to write up my methods which I am quite actively avoiding heeeheee... And because I really don't have any exciting pictures, I added a picture of Millie and Andrew enjoying some (much deserved?) pool time before lunch :)
