WASHINGTON — Today a measure was introduced to help ensure fisheries in the United States are resilient to changing ocean conditions, including the impacts of climate change. The Fisheries Improvement and Seafood Health (FISH) Act omnibus, which includes the Resilient Fisheries Act, will create a new program within the National Oceanic and Atmospheric Administration (NOAA) dedicated to ...
That is why, since 2008, we have been celebrating World Oceans Day every 8 June. Today, under the theme “Ocean planet: tides are changing,” it is essential to remember their important role in our lives. ...
2021 has been a sobering year for anyone concerned about climate change. We’ve witnessed record temperatures being set in Russia, the ‘Heat Dome’ in the Pacific Northwest, the devastating wildfires in Greece, and the catastrophic flooding in China, Central Europe and following Hurricane Ida in the US. This is a serious reminder that there is still a long road ahead to achieve ...
The University of Wisconsin-Madison has evaluated Madison Gas and Electric's (MGE) goal of net-zero carbon electricity by 2050, comparing it to the modeled pathways for the electricity sector in industrialized nations to limit global warming to 1.5 degrees Celsius. Relative to publicly available model results for carbon reductions through 2050, MGE's goal is in ...
The project aims to: Ensure market readiness of WaveRoller solutions by preparing processes for projects with 5-10 MW capacity, ahead of the EU target of 150 MW installed capacity by 2030 Facilitate the market uptake of wave energy by developing a scalable business and service model to support future WaveFarms totalling 200GW+ Develop a roadmap for global replication that ...
The Minerals Management Service (MMS) recently funded upgrades to the Ohmsett wave generator to improve the quality of waves so they more closely simulate ocean waves. While the old wave forms were adequate for testing oil spill response equipment, the waves were not close enough to ocean waves to satisfactorily evaluate alternative energy devices which are now being tested at Ohmsett. The ...

The southeast Indian Ocean (SEIO) exhibits decadal variability in sea surface temperature (SST) with amplitudes of ∼0.2-0.3 K and covaries with the central Pacific (r= -0.63 with Niño-4 index for 1975-2010). In this study, the generation mechanisms of decadal SST variability are explored using an ocean general circulation model (OGCM), ...
ORAS5 uses the same ocean and sea ice model as for ORAP5 and was produced using the V3.4.1 of the NEMO ocean model at a resolution of 0.25° in the horizontal and 75 nonuniformly spaced levels in the vertical. ORAS5 uses four-dimensional data assimilation of multivariate fields, including sea surface height from altimetry, ...
The importance of subtropical and extratropical zonal wind stress anomalies on Pacific Subtropical Cells (STCs) strength is assessed through several idealized and realistic numerical experiments with a global ocean model. Different zonal wind stress anomalies are employed, and their intensity is strengthened or weakened with respect to the climatological value ...
Although remote from human population centres, ocean circulation may connect these MPAs to sources of pollution – impacting how effective they can be. ...
A second study, published today by NOC scientists as a part of a special issue of Global Change Biology, investigates whether marine ecosystems will be altered as much by changing ocean currents, as they will be by ocean acidification, warming or de-oxygenation. Ocean currents shape the structure of marine ecosystems by creating the flow ...
The deep sea is an important habitat for a diverse array of marine life, yet if a prolonged oil spill were to happen, the complex ocean currents in and around this region of the North Atlantic would present challenges to predicting or understanding its impacts. Scientists at NOC have used the state-of-the-art NEMO ocean circulation model, ...
Aquatec Group are pleased to announce the launch of the latest addition to their Sediment? Solved range at Ocean Business in April – the AQUAlogger 310TY advanced turbidity logger. ...
This USGS Coastal Change Forecast model uses the National Hurricane Center’s storm surge predictions and National Oceanic and Atmospheric Administration wave forecast models as input. The USGS model adds information about the beach slope and dune height to predict how high waves and surge will move up the beach and whether ...
The Department of Ocean, Earth, and Atmospheric Sciences at Old Dominion University invites applications for a tenure-track faculty position beginning fall 2017. ...
Our work in the vast open ocean spaces, hundreds of miles from land is a crucial part of this assessment. ...
However the Subpolar Gyre is presently inadequately observed, and no ocean general circulation or climate model represents it accurately. UK-OSNAP will deliver enhanced understanding of processes critical to the improvement of physics in climate models through sustained observation of ocean circulation and fluxes, together with ...
In the case of the current the eddies create a resonant Rossby wave in the ocean basin, which because it is not completely closed, allows water mass to be exchanged with the rest of the ocean. ...
NOC scientists will be using global ocean models to identify the most effective way for low income countries, such as Madagascar, to adapt to climate change. ...
This tandem mission will improve our knowledge of tides in coastal and shallow seas and internal tides in the open ocean, while improving our understanding of ocean currents and eddies. Measurements of sea-surface height, or ocean-surface topography, reveal the speed and direction of ocean currents and tell scientists how much ...
