Resurrection Bay Sharks

https://vimeo.com/1031267933?share=copy

Science Communications film maker Rose Dalrymple followed us on our DSCT shark camera trap adventures in Resurrection Bay this last summer, and produced this short video clip introducing our project.

In this project, we are deploying our DSCT (Deep Submersible Camera Trap) – a Baited Remote Underwater Video (BRUV) benthic lander – together with the Passive eDNA & Sediment Collection Apparatus (PESCA) water sampler as well as additional environmental sensors deep in the waters of Alaskan fjords. The DSCT with PESCA is placed in the aphotic (light-less) zone at depths between 200 and 400 meters, and can record video and ocean data for up to 48 hours. As reported in our previous blogs, we use active deep red illumination which most deep sea organisms cannot see. We are using the DSCT to document where we can encounter the cold-water Pacific sleeper shark, and we are characterizing biodiversity by detecting environmental DNA of other marine organisms in the waters around the lander.

Under Antarctic Ice
This 15 min amazing video with sound shows underwater imagery from #McMurdo Sound, #Antarctica:

when he joined our NSF-funded Weddell Seal research project as outreach cinematographer. He did the diving, took and edited the video, and created the soundtrack - that is him playing the guitar, and he also used recorded #Weddell seal vocalizations.
This is an amazingly beautiful video to sit and enjoy during the holidays.
Happy Antarctic Holidays!

We catch sleeper #sharks in the Gulf of #Alaska, close to shore, in depths of 150 to 350m. We measure their size - here a research technician is measuring the width of the mouth. This shark is large, about 3.5m total length, but even at that size it is still immature. We then tag them with electronic tags and release them. The tags will later tell us where they go and what they do, and maybe more.
