FyB: Float Your Boat

Float Your Boat vil sette ut 400 trebåter på sjøisen i Arktis for å følge deres bevegelser med vind og havstrømmer fra Polhavet og ut i det Nordiskehavet som en del av skoleundervisning i naturfag.

Formålet med aktiviteten er å øke forståelsen for klimaprosesser, Arktis og betydningen av forskning gjennom aktiv involvering av skoleelever. Prosjektet er basert på Nansensenterets pågående aktivitet i havet nord for Svalbard.

2020 summer research school cruise: Useful Arctic Knowledge

In June, ten MSc students from the University of Bergen and the Western Norway University of Applied Science embarked on the coast guard vessel KV Svalbard to participate in the research school cruise near Svalbard, led by the Nansen Environmental and Remote Sensing Center. Their goal was to get hands-on experience during a scientific cruise in the Arctic.

CAATEX 2020 research cruise: Measuring the Arctic Ocean temperature below sea ice with sound

At this moment, the Norwegian Coast Guard icebreaker KV Svalbard is on a scientific expedition on the central Arctic Ocean with eleven scientists from different Norwegian and European institutions. Demanding operations are carried out to recover deep-water moorings deployed last summer. The moorings carry instruments to observe the ocean temperatures, salinity, ‘ocean sound’, carbon dioxide, and currents below the Arctic sea ice for one year. All this to calculate the ocean temperature below the sea ice.

CAATEX: Coordinated Arctic Acoustic Thermometry Experiment

During the MOSAiC drift, two sound sourcs in fixed moorings will transmit a signal which will be received on listen cables in 5 fixed moorings and four drifting drifting receivers hundreds of kilometers away from the sound sources. 

 The Arctic region experiences strong climate change, but yet the central Arctic Ocean under the sea ice is poorly observed and remains largely unknown. A particular focus in CAATEX will be to obtain regional to basin scale information about ocean temperature from acoustic thermometry and standard oceanographic instrumentation. A major effort will be to design and implement the acoustic thermometry experiment including fixed mooring and moving ship thermometry.
