Water depth: approximately 100 meters Temperature: Very cold (2 degrees Fahrenheit)

Today we officially crossed into tomorrow...if only for a little bit. Over the past couple of days we have been making our way steadily north, in order to drop off a member of the science party at St. Lawrence Island. This puts us very near the border between Russian and American waters. On our way back from that area today, we crossed over the International Date Line, putting half the ship into tomorrow!

Before we headed north, we sampled at one more station off the shelf. This was a deep station at 3000 meters (over 9000 feet). As we have done in the past, everyone broke out the Styrofoam cups and permanent markers, and then put them all in a mesh bag and sent them over the side attached to the CTD (an instrument that measures the conductivity, aka salinity, temperature and depth of the water column, as well as takes water samples from various depths in the water).

CTD
The CTD, which is used to measure properties of the water column such as conductivity (salinity), temperature, depth, chlorophyll (how much phytoplankton are in the water) and dissolved oxygen. Each big grey bottle attached can be triggered from the ship to close at a certain depth in the water, to collect samples of water from whatever depth the scientists on board decide are important.

Decorated Styrofoam cups
My Styrofoam cups that I decorated, before they were attached to the CTD. One has "NVMS" on it, which stands for Nooksack Valley Middle School, which is the middle school I worked at from 2006-2007.

Can you guess what happened to the cups after they were sent down to 3000 meters below the surface???? A hint...Styrofoam has lots of air in it (have you ever floated a Styrofoam cup on water?) and there is a lot more pressure under the water than above the water...

I'll leave you hanging until the next journal!
