NOAA is using data from a new current meter in New York harbor, operated by one of its academic partners, New Jersey’s Stevens Institute of Technology, to provide enhanced real-time information to mariners travelling through the nation’s second busiest port.
More than 800 acres of uplands in and near Acadia National Park will likely be flooded by the ocean if sea level rises 2 feet during this century, leaving 75 percent of the saltwater marshes along this part of central Maine's rugged coast with very little upland area to migrate into, according to a new U.S. Geological Survey study and maps.
An interagency team charged with improving how Washington’s coastal and ocean resources are managed has launched a new interactive website that supports “marine spatial planning.” Marine spatial planning brings together multiple users of Washington’s coast—including energy, industry, government, conservation, and recreation—to make informed and coordinated decisions about how to use marine resources sustainably. The process is similar to land-use planning but for marine waters.
In some of the first climate simulations of modelled wave conditions they also found a likely increase in wave height across seven per cent of the global ocean, predominantly in the Southern Ocean. These findings are derived from a study which seeks to understand potential impacts on coasts from climate change driven wind-wave conditions. The study will be published in the print edition of the journal Nature Climate Change on 25 April.
The Federated States of Micronesia (FSM) and the Kingdom of Morocco on Tuesday formally filed a proposal to use the Montreal Protocol treaty to phase down hydrofluorocarbons, or HFCs, super-greenhouse gases that are hundreds to thousands of times more potent in their warming impact than carbon dioxide. These factory-made chemicals are the fastest growing greenhouse gases in the U.S. and many other countries, and their production is projected to increase up to tenfold by 2050. According to a new paper by a team led by V. Ramanathan at Scripps Institution of Oceanography, UC San Diego, halting the production and use of HFCs is part of a key package of near-term measures that would significantly slow down sea-level rise during this century.
