Design Studies for Replacement of R/V DANA

advanced multidisciplinary research vessel that will place DTU Aqua in position being an attractive partner for international scientific projects.The multidisciplinary 65-m marine research vessel is designed and optimized for cost-effective fish stock assessment, hydro-acoustic studies and biological, chemical and physical oceanography based on DTU Aqua’s expected service profile in 2023.The following objectives have been prioritized:- Maximum capacity for hydro acoustic scientific performance- High efficiency in fish stock monitoring- High scientific multidisciplinary performance through versatile

hormones, and defend against pollutants. We have yet to find out what they are doing in these viruses, but for sure they are unique, unlike P450s in any other organism.”P450 enzymes, which constitute one of the largest enzyme superfamilies known, may also have major implications for understanding chemical effects both in the sea and in human disease processes.“We know some giant viruses may be linked to some forms of pneumonia, so gaining a better understanding of them will help us to develop ways of tackling those viruses,” explains David Lamb, lead author from Swansea University Medical

WHOI Names Murray Deputy Director & VP for Research

The Woods Hole Oceanographic Institution (WHOI) announced that Dr. Richard W. Murray has accepted the position of the Deputy Director & Vice President for Research of the institution. He will assume the office on September 1, 2019.A geochemist whose research focuses on interpreting chemical records of climate change and volcanism in marine sediments, Murray joins WHOI from Boston University, where he has been since 1992 and is currently a professor of Earth and Environment. Murray was director of the Division of Ocean Sciences at the National Science Foundation (NSF) from 2015-2018. In addition to

the compound under lab conditions. The position of the trigger on the seabed means it can be more readily replaced so this will need to last for approximately 10 years.”Professor David Bucknall (Photo: Heriot-Watt University)The project will focus on three critical stages, the partners said. The chemical design is currently underway and will be followed by laboratory and simulated field trials before independent external validation tests.The materials will then be commercially produced in sufficient quantities to begin offshore trials conducted by Subsea Sentinel in wells in the North Sea before

Subsea Mining: The Next Big Thing for UUVs

; HD cameras; conductivity sensors; ocean-floor magnetometers and laser sensors. Importantly, those AUV payloads largely require the REEs subsea mining seeks.Deep sea mining techniques are being polished in the wake of major offshore acreage awards. Deep sea miner, Ocean Minerals, says REEs are “17 chemically similar metals consisting of the 15 elements known as the lanthanides plus yttrium and scandium” and they’re of value due to their “unique magnetic, chemical and luminescent properties” and essential to makers of hybrid vehicles, mobile telephones, computers, etc. That&rsquo

NTNU post-docs, Ph.Ds and masters students are nearing their SmallSat launch day, after which North Sea AUVs will have taken a step toward being able to relay data to scientists onshore for long periods. Both SmallSats and AUVs will have hyperspectral cameras able to detect chemicals, metals, plankton or do survey work.The California-based Prof. Rajan is a senior scientist known for planning, executing and creating autonomous systems and robotics at NASA’s Ames Research Center. Prof. De Sousa leads an international network of AUV-keen scientists akin to NTNU’s.

The water in Abrolhos remains transparent, but it has finer, more soluble materials that get there and, on arrival, have been incorporated by organisms."For years, Evangelista has been researching the corals of the Abrolhos National Park in Bahia. The chemical information contained in the skeleton of the existing species, helps to recount the history of the local marine ecosystem, such as water temperature over time."Corals are organisms that, as they grow, form a skeleton, which is being stacked. The fabric that forms the coral is millimetric, all

AMOS researchers have just developed their own, “low-cost” spectral camera: “What’s hot about this research is that hyperspectral cameras (using chemical calculations) can measure all the colors of our (electromagnetic) spectrum, so it sees what you can’t see with your eyes. It can see the kind of metal a plate of metal is or it can look at a coral and see color that you can’t see with your eyes.”Martin Ludvigsen, an NTNU professor
