Ship departure and training
After the last lines were thrown off the dock, the RVIB Nathaniel B. Palmer left the
Punta Arenas port and began its transit across the Straits of Magellan to
the Argentine coast and into the South Atlantic Ocean.
March 6, 2009
The first day at sea was filled with safety briefings and operational
training. The ship’s chief mate instructed the science and technical
staff about where to “muster” (gather), how to keep exterior
water-tight doors “dogged” (closed with extra levers), and the
importance of the “gumby” suits (special protective immersion suits).
We all practiced putting on our life jackets and immersion suits and
getting in a lifeboat so that we will be prepared in case of an emergency.

A group of technicians onboard the Palmer support the scientists by interfacing with
the ship’s crew for research data collection. The marine technicians
trained us on exterior deck safety, where we’ll need to wear float coats
and hard hats at all times. Most of the sampling equipment we’ll use will
go into the ocean from this area. The hard hats are important protection
against overhead equipment and falling ice chunks that can form when the
ship works in polar waters. The float coats work like life vests but allow
more mobility for the wearer to effectively operate on deck.
The marine science technicians spoke about lab safety. There are several
“wet” lab areas where experiments using chemicals will take place.
These chemicals must be handled safely. The ship has special cabinets,
refrigerators, storage areas, and procedures for chemicals. Even the end of
the cruise was discussed briefly, as some samples and chemicals must be
shipped back at specific temperatures—all coordinated by the
technicians—and critical in many cases for the scientists to get the data

The last training of the day gave an overview of the computer network
onboard the ship and the array of data collected that are available for
scientists in real time. When the ship gets into the open ocean, underway
measurements of temperature, salinity, and other parameters will begin.
It will take about a day to pass south down the Argentine coast and another
two days after that to reach the first sampling site at Clarence Island, a
deeper-water (>600m) site just east of Elephant Island. The team will test
instruments in this control area, and also collect important background
measurements that can be compared with data collected later around
icebergs. During the transit we are anticipating some rough seas due to an
advancing low pressure system, so we finished the day by securing loose
items, prepping equipment, and calibrating instruments to be ready for the
first sampling station.
