Science one day, medical rescue the next

By Julian Race. The Ross Sea, Antarctica

What was supposed to be an ordinary science cruise to the Ross Sea turned into a rescue mission for the scientists and crew on the ice breaker research vessel Nathaniel B. Palmer. On January 10, 2012, the Palmer was conducting research in the Ross Sea, collecting data about nutrients and other ocean processes. At approximately 3:30AM, a distress call was received from a nearby fishing vessel. The vessel was reported to be on fire, and the situation was very serious. Captain Sebastian Paoni, Marine Projects Coordinator Al Hickey, and Chief Scientist Dennis McGillicuddy made the decision to halt science operations and make best possible speed to go help.


All of the science equipment was winched back onboard the ship, the laboratories were cleaned and secured, and the Palmer turned north and headed full-speed towards the last known location of the vessel in distress. Meanwhile, the Captain and his crew were in contact with the New Zealand Rescue Coordination Centre (RCC), the dedicated rescue operations command post for that area of Antarctica. The RCC was gathering all reports about the incident, and coordinating the response. The Palmer was not the only ship in the area, but was the nearest, most properly equipped vessel to handle serious injuries. At the time, the RCC reported that the Palmer was about 16 hours away from the scene, and there were also two other fishing vessels 30 miles away. The Korean research vessel Araon was also in the area and was reported to be about 24 hours out.

The reports from RCC were grim: the Korean fishing vessel Jeong Woo 2 was on fire, and of the 40 crew, 3 were missing and many were injured. The fire was out of control, and had already destroyed one of the vessel’s two lifeboats. Some of the crew had evacuated to the remaining lifeboat, but many were still stranded onboard the burning ship. The Palmer kept heading north, and all hands made ready for the upcoming rescue. The various scientists and support staff were assigned roles based on their skills and experience. Some would act as medics, others as rescue, recovery or general support. The ship was also preparing to take on up to 40 extra passengers. Every available space was made ready, as well as food and blankets for the victims.


About an hour away from the rescue, an all-hands meeting was called to discuss the rescue. The latest reports were better than expected, but still serious: the Jeong Woo 3, sister ship of the Jeong Woo 2, had arrived and evacuated all of the survivors from the burning wreck. Unfortunately, it was confirmed that three of the crew members had not survived the blaze, and an additional 7 were seriously injured and required immediate medical care. The Jeong Woo 3 was not able to properly treat the injured, and the Palmer, with a fully- equipped and staffed hospital, was asked to take on the injured and transport them to McMurdo station for evacuation to New Zealand.

The Palmer’s mission had shifted from rescue and recovery to medical transport. Arriving at 7:50PM on January 10, 2012, the Palmer came upon a shocking scene. The Jeong Woo 2 was still burning fiercely, with yellow flames leaping out of the pilothouse and superstructure, while thick black smoke billowed into the sky. The burning ship was wedged into some pack ice, and a short way off stood theJeong Woo 3. The Palmer’s crew adapted their plans and quickly made ready to take on the injured victims.


To transport the patients from the Korean ship to the Palmer, two zodiacs were put into the water. Each zodiac was manned with a helmsman, ship’s officer, medic, and deckhand. The zodiacs took turns ferrying the patients from the Korean ship back to the Palmer. The patients who could walk were helped up the side of the ship by way of the boarding ladder, while the serious cases were lifted, boat and all, up to the Palmer’s helicopter pad, where a team waited to carry them directly to the ship’s hospital.

After multiple trips back and forth, all of the injured fishermen were on the Palmer and ship’s EMTs began treating them. The ship then turned south and began making way towards McMurdo station.
The transit to McMurdo went quickly, with the Palmer using all of its sophisticated sensors and systems to plot the fastest, safest route through the ice to McMurdo. The ship would break its way into the ice about 16 miles from the station, and a medical team would fly to the ship in helicopters to offload the patients. 32 hours after leaving the Jeong Woo 3, the Palmer arrived at the McMurdo ice edge and began pushing her way into the ice. Being an icebreaker, the 2-3 foot thick sea ice was no problem. The Palmer stopped at a section of ice identified by an earlier reconnaissance flight as flat and stable enough to support the helicopters. 

Once the ship was secure, the crew carefully examined the ice around the ship, and marked off a safe landing zone using food coloring from the ship’s galley. The medical team from McMurdo arrived shortly after, and landed on the ice a few hundred feet away from the ship. The crew of the Palmer again went into action, performing the patient offload quickly and safely. The patients who could walk were gently escorted down the gangway, where a team was assembled on the ice, and rescue sleds that the medical team brought from McMurdo were used to transport the patients from the ship to the waiting helicopters. The seriously injured patients were carried from the hospital to the helo deck in a litter – a lightweight stretcher – and placed into a zodiac. One medic rode with the patient as the ship’s crane lifted the boat over the side and lowered it down to the ice. Again, the ice team dragged the patients to the helicopter, where they were loaded on and sent on to McMurdo.

Once all of the patients and medical personnel were safely on their way to McMurdo, the Palmer secured for sea and started back towards the Ross Sea to continue the science mission where they left of. The scientists, support staff, and crew of the Nathaniel B. Palmer worked as a team to respond to this serious incident, and played a key role in the response to this maritime tragedy.


Mount Erebus, Ross Island, Antarctica


Mount Erebus (English pronunciation: /ˈɛrɨbəs/) is the second highest volcano in Antarctica (after Mount Sidley), and the 6th highestultra mountain on an island. With a summit elevation of 3,794 metres (12,448 ft), it is located on Ross Island, which is also home to three inactive volcanoes, notably Mount Terror. Mount Erebus is part of the Pacific Ring of Fire, which includes over 160 active volcanoes.
The volcano has been observed to be continuously active since 1972 and is the site of the Mount Erebus Volcano Observatory run by the New Mexico Institute of Mining and Technology (source wikipedia)

Mount Erebus is the site we visited recently. We will be returning to the region upon completion of our cruise toward the beginning of February.

Back on Track!


Finally, we are back on track!  It looks like science has successfully resumed after the rescue operations, which, by the way, went very well. Needless to say they were very organized. Hats off to the crew, passengers and guests of the Nathaniel B. Palmer. There is no way these operations could have been dealt with more professionally. 

The ban on sharing photos and intimate details about the incident still holds to protect the privacy of the fishermen.  More on this soon!

Now, after a two-day hiatus we are back on track with our sampling protocol. The next stations to be occupied and sampled will be Station #7 followed by Station #8. The former is the site of the Ross ice shelf water while the latter features a high biomass (HB#1, with high chlorophyll concentrations).  MODIS satellite was used to describe HB#1 based on fluorescence values, while Temperature-Salinity plots will be used to characterize the distinct ice shelf water. The usual sampling protocol includes trace metal sampling followed by CTD casts from different depths and net towing. As mentioned in one of the earlier blogs the PRISM project hinges around 4 major hypotheses. One such hypothesis is that sea ice tends to melt during the austral summer (December-February) because of high solar incidence (24hrs of sunlight) and this water mass is a potential source for new iron for photosynthesis to take place  unhindered, resultantly allowing biomass to accumulate.

Science suspended for a day or two!


All is well aboard our research ship which participated in a rescue of fishermen from their burning vessel (Korean fishing vessel).  We have been asked until further notice not to communicate any details regarding this situation out of respect for the privacy of those we took aboard.  The media has many articles regarding this situation which can readily be found online.

The hydrography group

Eddies

En route to our next sampling station we spotted two eddies (a smaller, eddy # 1 and a little larger eddy #2) and stopped to sample them using CTD and trace metal tow fish. The 'M' in PRIMS - RS stands for mesoscale  processes and it looks like there is going to be a lot of those in the Ross Sea. One way to detect these oceanographic features is by looking at satellite pictures for chlorophyll patterns - usually circular or elliptical in shape, with high concentrations at the edges. The moving vessel profiler, which is towed from the ship, is sending in images and a computer software onboard of NBP (Nathaniel B. Palmer) is analyzing the pictures in near-real time  and decisions for where to exactly take samples from will be based on these observations.

On the hunt for CDW (Circumpolar Deep Water)

Now that we have finished sampling Station #3 we are on an incessant hunt for CDW. This mass of water has distinct characteristics and along-track sensors mounted on the MVP (moving vessel profiler) will be able to identify such properties of the CDW as salinity, temperature, etc. 

In the meanwhile, however the sea-ice is always a pleasure to look at and never ceases to surprise us. At times this white 'desert' is punctured by large animals as Emperor penguins and seals (pictured below). Other unidentified birds do, from time to time, hover over the ice in search for food.
