- The OSNAP zooBy Donald Slater The walk-in fridge in the main lab of the RV Neil Armstrong has for the past 5 weeks functioned as anything but a fridge. With storage space at a premium, it has hosted much of the moored instrumentation, including the microcats that measure ocean temperature and salinity, and the aquadopps that measure … Continue reading
- Stories in Greenlandic Place Names along the Southeast Coast (Straneo OSNAP AR69-03)By Aurora Roth On September 1, almost halfway through the cruise, we passed through Ikerasassuaq (“big sound”, alternately known as Prince Christian Sound). It’s a long narrow channel that demarcates the north end of Uummannarsuaq (“large heart-shaped place” or Cape Farewell), at the southern tip of Kalaallit Nunnat (Greenland). Travelling through this fjord marked our … Continue reading
- When the science stopsBy M. Yoder, Boston College We boarded the R/V Neil Armstrong as scientists on a mission to collect data and redeploy moorings, and while someone is on shift and working 24/7, it’s not all of us at the exact same time. So, what goes on when we’re not deep in the action? Many of the … Continue reading
- Mooring Operations along the CF ArrayBy Hiroki Nagao On 19 August 2022, the R/V Neil Armstrong set sail from Reykjavík to the cold, stormy waters of the Subpolar North Atlantic. This region consists of a complex network of surface and deep ocean currents, which together play a critical role in the Earth’s climate system via the transport of heat, freshwater, … Continue reading
- Learning the Water Sampling RoutineBy Monica Nelson Many of us on the CTD watches are physical oceanographers but we were charged with collecting biogeochemical data to complement the OSNAP mission. In addition to the usual water sampling to calibrate the salinity sensors on the rosette, we’ve been collecting water samples to calibrate oxygen sensors and samples to measure ocean … Continue reading
- Straneo OSNAP: Cruise AR69-03 introBy Monica Nelson Out in the Irminger Sea, our world is at once both very small and very expansive. Confined to R/V Neil Armstrong our world consists of the instrument-laden lab, the sea-spray-soaked deck, and the endless grey-blue ocean stretching for as far as the eye can see – or as far as the fog … Continue reading
- Labrador Sea Weather Forecasts – Meet our Meteorologist and Weather Technician aboard the RV MeteorBy Anne-Sophie Fortin Every day aboard starts with looking up the weather forecast from our favourite meteorologist aboard: Julia Wenzel. Her forecasts are central to the planning of our day-to-day operations on the ship. While on land we may be more interested in whether a day will be sunny or rainy, here at sea we … Continue reading
- Gliders Recovery with a Rescue ParachuteWe returned where we investigated an eddy last week to recover our two gliders that have been collecting data since then. Because of the strong winds, low visibility, and high waves, we could not use the Zodiac to recover the gliders this time. Thus, a “rescue parachute”, originally designed to rescue a person that would … Continue reading
