Gone Fishin'


On Thursday we headed back out to sea.  This was going to be a short fishing cruise to collect samples of Ice Fish for the IcemiR project that is studying the evolution of microRNA control in Antarctic Fish.  I have no idea what that means, but I was more than happy to help them catch fish.

Heading into some Brash Ice (<2M)

After sailing for about a day we reached one of the fishing grounds.  Hugo Deep is about 640m (2099 ft) deep so with the trawl dragging on the bottom we had about 1,500m (4,921ft) of cable pulling the net.  Each cast took about 3 hours total so it was a lot of hurry up and wait.  Once the net was on the back deck the science team went to work looking for samples.  The goal was to keep the samples alive and return the unwanted by-catch as quick as possible to minimize impact.

We got really lucky with the weather, we had pretty calm seas and it was in the mid 20's with 10-15kn wind.  We were only on the back deck for about an hour at a time so it wasn't that bad.

On Friday night we fished from 6:00 PM to 6:20 AM, It was a long night on the back deck and helping with samples in the wet lab but being in good company made the experience enjoyable.

Palmer Station has science lectures on Tuesdays so in a few hours, I'll have a little more knowledge about the research.

After the science lecture on Ice Fish, we're watching SHARKNADO!!!!  It's gonna be a wild night.

Journey to Palmer Station


My travels so far:
  • Flight from Denver to Punta Arenas, Chile.
  • Two weeks in Punta Arenas waiting for the vessel to arrive.
  • Four days on the Laurence M. Gould crossing the Drake Passage.

While at Palmer Station I’ll be working with the winter station crew to develop safe work practices and evaluate the facility to see if there are opportunities to implement "Prevention through Design" type concepts, you know, safety stuff.

Similar to deploying through Christchurch, NZ, one of the first things participants do is pick up their Extreme Cold Weather (ECW) gear.  The gear is a little different since working on the vessel requires protection from the wet marine environment.  It's mostly Gortex type gear, no "Big Red" parka this time.

After experiencing weather days due to some massive storms in the Drake passage, the vessel finally arrived six day late.  During the three-day port call, science samples are off loaded, new supplies were loaded, the vessel is refueled.  Within our program, about half of the crew are being swapped out with replacements.  The boats are chartered so the task of operating and maintaining the vessel fall under a different company.  We're only responsible for the labs and science operations.  During port call, we moved out of our hotel and onto the boat.  Normally it's two people to a room but there are not that many on the cruise so we each got our own room.

Berthing on the LMG
During our time in Punta Arenas, we did take a day off to go explore the city.  Its the middle of winter here so the weather was cold mixed in with rain and snow.   No one complained though after all, cold and snow is kind of what we do.



There were stray dogs all over the city.  This guy followed us for most of the day so we named him Osito which is Spanish for "Little Bear."

We checked out the Punta Arenas Cemetary.  The cemetery had a very unique history and was rated by CNN Travel as one of the top 10 most beautiful cemeteries in the world.  The cold, snowy day made for a somber backdrop to the thousands of graves.

Finally, the time came to get underway.  After weeks of waiting, we were finally starting our four-day journey south.

Sunset While Getting Underway

Not knowing how I was going to handle the seas, I took the "Recommended" dosage of Dramamine.  That stuff could tranquilize a horse!  I ended up going from a full 50mg pill every 6 hours to 1/2 a pill with breakfast and one before bed.

Sunset on my first full day at sea.

We had an almost perfect crossing of the Drake Passage.  Swells ranged from about 6 to 12 feet compared to the 30'+ swells just a week before.  We crossed what they call "Lake Drake" with calm seas and no major weather.  My coworkers are giving me a hard time that the bad weather always happens on the North Bound leg of the journey so we'll see how that goes in a few weeks.
Calm Seas on "Lake Drake"
 On the last day of the trip, I slept in because the seas were calm and we had to slow down for ice (Made for good sleeping).  Being a bit sleep deprived and medicated, falling asleep is easy but getting good sleep is challenging.  I woke up to daylight and the first sighting of land.  It was an incredible feeling to know that I was back in Antarctica.

Early morning arrival at Palmer Station.

Tomorrow morning we are going on a four-day fishing cruise to attempt to catch some science samples.  I'll make sure to get another post up in a more timely manner.
