How Does River Outflow Impact Coastal Sea Level?

A new study led by the Woods Hole Oceanographic Institution (WHOI) has uncovered a new factor affecting coastal sea levels.Tides, winds, waves and even barometric pressure have been known to play a role in the ebb and flow of the ocean in coastal areas. According to the recent study, river outflow could play a role in sea level change as well.The study, published July 9 in the journal Proceedings of the National Academy of Sciences, examined decades’ worth of river level and tidal data from gauges installed throughout the eastern U.S. The researchers then combined that data with information on

Old Sea Ice is Disappearing from the Arctic Ocean

Sea ice grows throughout the fall and winter, and melts throughout the spring and summer. But not all Arctic sea ice melts; some portion of the ice survives at least one melt season, persisting throughout the summer months. This ice is usually thicker and more resistant to melt than ice that's less than a year old, and therefore more likely than first-year ice to survive the coming melt season. As Arctic sea ice often reaches its maximum extent around late February or early March (around the ninth week of the calendar year) that's a good time to measure multiyear versus first-year ice.In the

Switch from Leaded Petrol has Reduced Ocean Pollution

New research shows the first observed reduction in lead concentrations in the surface waters of the seas around Europe since the phasing out of leaded petrol.Lead has no biological function, and is toxic to humans and marine organisms. The study, published in Geophysical Research Letters, is based on samples of the Celtic Sea taken during a series of research expeditions on board the Royal Research Ship (RRS) Discovery. The results show that there has been a four-fold reduction in the concentration of lead in the surface waters of European shelf seas compared to measurements undertaken two to three

Oil Recovered from Sunken Ship Thorco Cloud

Jaya Salvage Indonesia early last year. Bumi Subsea provided remotely operated vehicles (ROV) and the dynamically positioned Surf Allamanda, owned by Bourbon Offshore. This served as the work platform during the salvage of the trapped fuel by using the Moskito hot tap tool developed in Norway by Miko Marine. Thousands of sunken ships along the coast of Norway represent pollution dangers from the fuel trapped inside their hulls. This prompted the Norwegian Coastal Administration to invite Miko Marine to devise a method for removing it. The result was a unique tapping machine, known as the Moskito
