A joint research effort between the University of Hawaii at Mānoa's Hawai'i Institute of Marine Biology(HIMB), University of Tokyo, the Japanese National Institute of Polar Research and the University of Florida has shed new light on the hunting bRead More
Australian Institute of Marine Science (AIMS) scientist Dr Katharina Fabricius has led two research expeditions, with researchers from six countries including Papua New Guinea (PNG), to study three natural CO2 seeps in Milne Bay Province, PNG. This unique location is the only presently known cool, CO2 seep site in tropical waters containing coral reef ecosystems. The study has given scientists unprecedented insights into what coral reefs would look like if greenhouse gas emissions and resulting ocean acidification continues to increase at present rates.Read More
“The findings add fuel to an already fierce debate in the research community on how the echolocation sound is produced”, says Josefin Starkhammar.,
The beam projections have different frequencies and can be sent in different directions. The advantage is probably that the dolphin can locate the object more precisely.

Dead zones form where microscopic plants, known as phytoplankton, are fertilized by excess nutrients, such as fertilizers and sewage, that are generated by human activities and dumped into the ocean by rivers, or more rarely, where they are fertilRead More
For some years, researchers have pinned their hopes on the ability of weed-eating fish to keep the weeds at bay while the corals recover following a major setback like bleaching, a dump of sediment from the land, or a violent cyclone.Read More
Part-time marine archaeologists Hans and Roz Berekoven - who are married to each other - said their find was unlikely to yield any treasures as the ship had been a British cargo vessel, but it could add to knowledge of trade then, the Jakarta GlobRead More
This behavior seems to imply a map sense from which the creatures read either absolute or relative location from at least two coordinates.
Direction is one thing but how about position?,
The results demonstrate for the first time that longitude can be encoded into the magnetic positioning system of a migratory animal.
“The fact that the animals live continuously for thousands of years amazes me,” said Dr. Nancy Prouty of the U.S. Geological Survey Pacific Coastal and Marine Science Center, who analyzed the coral samples that were collected by the USGS and colleagues as part of several ongoing deep-sea coral ecosystem studies between 2003 and 2009. “Despite living at 300 meters and deeper, these animals are sensitive to what is going on in the surface ocean because they are feeding on organic matter that rapidly sinks to the sea floor.Read More
