It has thrusters on all sides that allow it to remain “on station” for a particular site so that it can deploy science assets from the starboard and aft sides of the main deck. This is particularly useful for coring, as different cores types can be deployed efficiently at the same site. https://images.squarespace-cdn.com/content/v1/5ba299727c93278b5b0e72f5/1552939024413-SEMN4WNE92G2XKBSL92R/9+TH+megacore+montage.jpg THOR Blogs - Hammertime: THOR’s Cores Despite nearly 50 years of collecting and refining the coring process, the one constant is mud. Everywhere. Especially for the samples from the Megacorer which need to be handled with utmost care in order to preserve the seawater/seafloor mud and the interface between them.

Palmer Peter is a postdoctoral researcher with TARSAN hailing from the University of East Anglia in the United Kingdom. Usually his field research takes place in the distant and warm Indian Ocean making observations of ocean currents and the fresh water that exchanges from the ocean into the air during the seasonal monsoons. Peter finds himself out of his element, you might say, in the icy reaches of Antarctica, but has taken to it well, helping to deploy the various TARSAN ocean instruments (including the CTD), creating visualizations of the ocean data as it arrives from the instruments, and providing hilarity through unending witty sarcasm to lighten the most mundane of activities. https://images.squarespace-cdn.com/content/v1/5ba299727c93278b5b0e72f5/1552063131880-M263MK5VCZWCW9EQQ2B4/Pic+of+Thwaites%21.JPG THOR Blogs - Life on the Research Icebreaker Nathaniel B.

Lars Boehme approaches a nearly one ton male elephant seal to see if he is a good candidate for a tag. The seal sees this as a challenge and expresses himself with bared teeth and a deep throated growling (that can really only be described as a very long, very scary belch). The trick to managing these encounters, according the Lars, is to appear taller than the seal. We were glad that he was the expert. Within a few seconds of looking the seal over, he walked away. The seal was still molting. If Lars attached a tag, it would soon fall off as the seal continued to shed its fur.

The “tag” - essentially a smaller version of the CTD - hitching a ride to validate measurements by comparing them to the CTD’s. Each tag is actually a tiny computer, battery and satellite transmitter (the antennae). The location, salinity, pressure and temperature for the depths the seal dives is transmitted each time the seal surfaces. The computers themselves are handmade by the Sea Mammal Research Unit Instrumentation Group. Each computer is hand assembled, and while the hardware is modular, the programming can be modified to gather a variety of data types, from studies in seal behavior to information about a variety of ocean environments and locations. https://images.squarespace-cdn.com/content/v1/5ba299727c93278b5b0e72f5/1551025759890-FF3P6PNICTGUCLTA9HEL/seal+tag+14.JPG THOR Blogs - Island Days (Part II) - TARSAN Partners with the Natives - Seals! This Weddell seal is not masquerading as a unicorn. The unique payload cap she is wearing is called a “tag”, a device created more than a decade ago by Dr. Lars Boehme, physical oceanographer at St. Andrews University in Scotland. The tag is a small computer that collects oceanographic information around Antarctica over the period of a about year. The “horn” transmits (by satellite) salinity and temperature with depth and location to a web application so that scientists can monitor their partners in near real time.

The path of the Antarctic circumpolar current brings it in contact with many other bodies of water, including the Southern Ocean, the Atlantic, the Indian and the Australian oceans. The ACC incorporates bits and pieces of those water bodies which then become part of the CDW. Amazingly enough, each of their contributions to the CDW can be identified by information such as temperature, salinity, biota and more. These data aren’t just thumbprints of their source, they also tell us about the interaction and extent of these characteristics. It tells us that ocean water is dynamic and interconnected. https://images.squarespace-cdn.com/content/v1/5ba299727c93278b5b0e72f5/1551027891966-7UZ2DQQXQB5ZXX08B53R/tagged+seal+in+water+3.JPG THOR Blogs - Island Days (Part II) - TARSAN Partners with the Natives - Seals!

The larger CTD device, also not terribly glamorous, can gather a lot of data in real time, if only in one spot. Its sensors send the information to a computer on the ship all during its trip to the deep. The large gray cannisters are like giant test tubes that can be signaled to open during its passage, sampling the ocean water. Samples can then be used to measure things like chlorophyll (the amounts of which can serve to tell scientists how well the phytoplankton are doing) oxygen in the water. They can also be preserved for future science that will be conducted at land-based laboratories following the cruise. The profiles provided by CTD’s have wide application for ocean modeling. for THOR, the temperature and salinity profiles are used as part of calculating the sound velocity that provides the multibeam sea floor bathymetry data. https://images.squarespace-cdn.com/content/v1/5ba299727c93278b5b0e72f5/1551027474351-TU9KLOYJ2VJT9R4X5E6I/seal+tag+4.JPG THOR Blogs - Island Days (Part II) - TARSAN Partners with the Natives - Seals! Seals are large and potentially dangerous animals, so they need to be sedated in order to attach the tag. Lars and his team are very experienced and very quickly settled the seal down in preparation for tagging. In addition to attaching the tag, they also record the seals size, approximate weight and overall health.
