A New Remotely Operated Sensor Platform for Interdisciplinary Observations under Sea Ice [PDF]
Observation of the climate and ecosystem of ice covered polar seas is a timely task for the scientific community. The goal is to assess the drastic and imminent changes of the polar sea ice cover induced by climate change. Retreating and thinning sea ice

Spatial Representation of NOAA’s Remotely Operated Vehicles (ROVs) Dive Tracks
The oceans make up about 70% of the earth’s surface and serve as habitats for many deep and shallow creatures. In depths of about 50 meters and more, deep-sea corals and sponges occur mostly along seamounts, continental margins, undersea canyons and ridges. They, deep-sea corals and sponges, play a key role in supporting the health of the ocean as they

New Compounds From the Deep‐sea Sponge Mycale lingua
The focus of this study is the scarcely investigated sponge Mycale lingua, found commonly in the North Atlantic Ocean. In total, four compounds are isolated and characterised from three combined M. lingua individuals. Structures are fully elucidated through HR‐LCMS and NMR spectroscopy (1H, COSY, HSQC, HMBC).

Benthic habitat mapping in the Olympic Coast National Marine Sanctuary: Classification of side scan sonar data from survey HMPR-108-2002-01: Version I [PDF]
In September 2002, side scan sonar was used to image a portion of the sea floor in the northern OCNMS and was mosaiced at 1-meter pixel resolution using 100 kHz data collected at 300-meter range scale.

Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

Precision and accuracy of fish length measurements obtained with two visual underwater methods [PDF]
During the VITAL cruise in the Bay of Biscay in summer 2002, two devices for measuring the length of swimming fish were tested: 1) a mechanical crown that emitted a pair of parallel laser beams and that was mounted on the main camera and 2) an underwater

In situ observations of fish associated with coral reefs off Ireland [PDF]
The abundance and behaviour of fish on and around coral reefs at Twin Mounds and Giant Mounds, carbonate mounds located on the continental shelf off Ireland (600-1100. m), were studied using two Remotely Operated Vehicle (ROV) dives.

ROV – Remoted Operated Vehicle
Hovudmålet med prosjektet var å bygge ein slitesterk og brukarvennleg observasjonsklasse ROV som kunne brukast ned til 20 meter. ROV står for Remotely Operated Vehicle som på norsk vert kalla fjernstyrt miniubåt og prosjektet omhandla planlegging, prosjektering og konstruksjon.

Recovery at Morvin: SERPENT final report [PDF]
Recovery from disturbance is poorly understood in deep water, but the extent of anthropogenic impacts is becoming increasingly well documented. We used Remotely Operated Vehicles (ROV) to visually assess the change in benthic habitat after exploratory ...

Light Transmission Through Arctic Sea Ice - Large-Scale Studies on Seasonality and Spatial Variability [PDF]
Arctic sea ice has declined and become thinner and more seasonal during the last decade. One consequence of this is that the surface energy budget of the Arctic Ocean is changing.
