Oceanic responses to climate and human interactions have been studied for decades. In recent years the effects of increasing ocean acidity have been featured, with stark images of coral reefs being decimated by bleaching.
University of Otago, New Zealand, researchers have described a new genus and species of dolphin from the late Oligocene. In their paper, "A new dolphin with tusk-like teeth from the late Oligocene of New Zealand indicates ...
A team of scientists led by a Brown University researcher has developed a new method for monitoring when deep sea methane deposits convert to gas and rise toward the seafloor in amounts that were previously too small to detect.
South Africa boasts some of the best fossil records on Earth. Fossils are found in strata and rocks in many parts of the country. Some are billions of years old.
Researchers have used nearly half a million fossils to solve a 200-year-old scientific mystery: why the number of different species is greatest near the equator and decreases steadily toward the polar regions. The results—published ...
Studying changes in marine biogeographic patterns and the factors impacting these patterns over geological time can help scientists understand current responses in organisms due to human-driven climate change. For instance, ...
Researchers have created a map of oceanic "dead zones" that existed during the Pliocene epoch, when the Earth's climate was two to three degrees warmer than it is now. The work could provide a glimpse into the locations and ...
Researchers have developed and demonstrated a robot capable of sorting, manipulating, and identifying microscopic marine fossils. The new technology automates a tedious process that plays a key role in advancing our understanding ...
A chemical analysis of sediment cores from the North Pacific Ocean show a consistent pairing of volcanic ash and hypoxia, a low ocean oxygen condition spanning thousands of years, during times of rapid climate warming at ...
Upper ocean heating in the equatorial Pacific—a key oceanographic region in Earth's climate system—is likely to make the East Asian monsoon season wetter, according to a study co-authored by a Rutgers researcher.
