The single channel seismic system was also deployed and although we are having some minor problems with it we plan to have it working in short order. Multibeam data is being collected concurrently and the data look good. Initial observations indicate that the data from the Simrad system are as good or better than the previous Seabeam system. Neither system works in the ice. We have yet to evaluate the multibeam in bad weather.

FUEL ON BOARD (@ 0000): 267,300 REMARKS: Well shucks, to continue along the slope involved in Dr. Jacobs ANSLOPE study, we had to cut through some brash ice. At least that's how it looked when we entered. MTs maintained a watch on the maggie, trailing 900 feet behind us. Before anyone was really aware of the situation the ice closed in behind us, putting dear Maggie in dire straits. The ship was stopped and the MTs started to winch in the sensor till all but about 300 feet were back on board. At this point it caught up. The bridge backed up, hoping the backwash would dislodge the cable. Tried this technique 3 times to no avail, breaking the cable. Cable laid on the ice and plans were made to get a hold and try again. A quick conference and a look at the ECDIS showed we had drifted north during all this and the chance that the cable may have trailed underneath the ship was possible. It was decided it would be prudent to give up rather than run the risk of tangling the cable in the prop. We waved bye-bye and continued on. Multibeam data has been looking good. Dr. Jacobs glad we didn't waste a whole lot of time trying to rescue the old maggie. Merry Christmas from all of us here on the NBP. Don. MPC.

Jesse was very thorough in his preparation of the guns. All hands turned out for possibly the most exciting thing to happen this trip. Mates did a splendid job of keeping us out of the wind during our preparation. As it was, it proved to be a chilly day on the back deck. Deployment went smooth, with everyone knowledgeable of their task at hand. Only problem that surfaced was a leaking number 6 gun that couldn't be fixed with the time allotted so was deployed but turned off. Scientists agreed to go with the single channel streamer due to noted ice in the study area. There wasn't much but agreed it could be worse over the horizon. Everything was deployed successfully and came on without a hitch. Thank you everyone. Don. MPC.

Unremarkable day towing seismic gear. In the early morning hours gun #3 developed a nasty leak causing the compressor safety's to turn off the compressors. Thought was we were going to have to retrieve the guns to drain them of water and rebuild. Jesse placed a call to Jay Ardai for guidance and was told to try bleeding air into each gun a little at a time to slowly push out any water that may have entered. Fortunately it worked and we had the guns back on line within an hour. Currently gathering seismic, multibeam, and magnetic data on a flat sea. Oh, yeah, Happy Solstice to everyone. Don. MPC.

CTD casts were first followed by a tow of the 1-m2 MOCNESS. After this we returned to the same location and deployed the ROV and placed the ice collection team on a floe near the ship. An under ice dive was then made along with a second series of CTD casts. The BIOMAPER-II was placed in the water at this station so that the transducers could be calibrated. Once this was completed we did another 1-m2 MOCNESS tow followed by another CTD cast. At day's end we were underway for Palmer Station.

Since ice conditions were very dynamic, a zodiac was placed on the floe in case the team needed to quickly evacuate the area. Following the ice party work, a CTD cast was completed. From here we proceeded to station # 1 arriving there at 01/0258LT (02/0658GMT). A CTD cast was completed at this location but the planned deployment of the ROV was cancelled due to the strong currents encountered and the associated drifting of the ship. We departed station #1 towyoing the BIOMAPER-II while heading for station #13. Approximately 6 hours into the transit we stopped to exchange the BIOMAPER-II with the 10-m2 MOCNESS. We continued our steam and concluded the 10-m2 MOCNESS tow about one hour before arriving at station #13 at 02/2052LT.

Several science activities were done at this station. First the ROV was deployed for under ice observations and the ice sampling team placed on the near the ship. Once these activities were finished a CTD cast was made followed by a Reeve net and then a 1-m2 MOCNESS deployment. It was then decided to take advantage of the good lead we were in and have the divers work in a good open area 200 meters ahead of the bow of the ship. While the divers were working a series of short CTD casts were taken.. Once the divers were back on board, three Tucker trawls were performed. We have started discussions with the LMG on our escorting them to their next process station. Because of time constraints and the need to start the northern portion of the survey grid, the Chief Scientist has dropped station # 25 and 24 from the grid survey plan. By 29/2223LT we departed station #26 and were en route directly for the LMG with the BIOMAPER-II astern. Chris Shepherd Raytheon Polar Services Company Marine Projects Coordinator R/V NATHANIEL B.

The first was for microstructure profiling using the CMiPS and the second was a standard CTD measurement going to the bottom. Following this we proceeded towyoing the BIOMAPER-II to station # 49, which is south-east along the transit line, arriving there at 25/1350LT. The CTD system was first performed and then the ship was repositioned to allow ice sampling and ROV operations. In an attempt to capture surface samples, a reef net and then a vertical net were deployed before performing a Tucker Trawl. By 25/2206LT we were underway to station # 40 with the BIOMAPER-II in tow.

After these activities were finished a CTD cast was taken followed by a Tucker trawl. An under ice dive was under consideration before leaving this station but the cold temperatures and the lack of krill, as verified by the ROV, made it logical to cancel the effort. By 23/1632LT we were underway with the BIOMAPER-II in tow heading for station # 63 which was approximately 16nm away.

By mid-day we were heading east on the track line toward station # 76 but heavy ice conditions required both ships to turn back. After travelling about 5 nm the LMG found a suitable spot to establish Process site #1 (68*42'S, 076*11'W). Some equipment and samples were then transferred between ships. Before leaving this location a CTD cast and BIOMAPPER calibration were completed. The NBP then proceeded toward station #76 with the objective of reaching station #77 by tomorrow morning.

Four CTD stations were completed followed by the deployment of the Benthos SeaRover ROV which operated at a distance of approximately 100 meters from the ship. Following this the 1-m2 MOCNESS was towed for nearly three hours and then the 10-m2 MOCNESS was deployed for two and one half hours. All systems seemed to be working well following some adjustments and were declared ready for the survey element of this cruise.

I was going to let it slide and then remembered that you need the metrics (Oh how I love metrics!). So - b/w you and me - the metric should be SS. Things here are going fine. It all just hit me yesterday and I am dreaming of sunny summer. It is all going fine but there are subtle games going on that I have just stopped wanting to play. How are things in the office? I hear we are isolated from the rest of Marine Ops? Is it noisy? Bob said something about the lighting? Not really looking forward to that but summer sounds good. Hope you are well Tim! I should be back in the office around 29May02. Cheers- Alice Marine Projects Coordinator R/V NATHANIEL B.

We towed the MOC1 while traveling from station 57 to station 58. The tow proved fruitful as we had our best catch of krill to date. Seabird and mammal observations continued as visibility allowed.

We are in the south part of Marguerite bay near George IV sound and are in a good deal of ice - a nice change. We completed station 55, entering loose pack a few miles before arriving. After station 55, we attempted to get to station 56 but ended up a bit short. It was decided that the time that it would take to get there would not be worth it so we did station work approximately 5 miles from the actual station 56. Station 56 consisted of an ROV deployment, an APOP deployment and a CTD cast. We were hoping to get a MOC1 tow in but the conditions did not allow it. The ice here is fairly dense older pack ice with thin ice in between. Everything is covered in a thick layer of snow. BG-246 did ice sampling at station 55 (or what was supposed to be station 55) and had to dig through 1.5m of snow before they got to ice and then pulled a 2.5m ice core. There is a lot of brown algal growth (mainly diatoms) under the ice and snow. Approximately 30 Adelie penguins, 1 Emporer penguin (a rare sight), and several crabeater and Weddell seals spotted throughout daylight hours. Our grid has us heading NW to station 57.

The sun was shining, the clouds were few and the scenery was incredible. We are continuing along the survey grid and have completed stations 34 - 37 in the northern part of Marguerite Bay. We met up with the LMG at 0700 local near our station 35 to exchange supplies (various chemicals, nets, live krill, and other supplies). The visit was brief but it was great to see our colleagues. This also presented a prime photo-shot opportunity for the two ships. The bottom topography in this area was quite erratic keeping the BIOMAPER watch on their toes as we towed the BIOMAPER through water of ever-changing depth. The bird observers had an interesting day in that they only saw very few birds. The acoustics also showed very little back-scattering in the water column. A beautiful area but it seems very barren of marine life. Hoping for more days like today, Alice Doyle Marine Projects Coordinator R/V NATHANIEL B.

We started a practice station at approximately 0900 local time testing the CTD, the APOP, the BIOMAPER and the MOCNESS (how is THAT for acromyms?). The various operations took a bit more time than expected but valuable lessons were learned. We should be set to begin the station work tomorrow.
