Climate change affects ecosystems worldwide, but how do conservationists decide which of planet earth’s ecosystems are most in need?
A team of researchers investigate why the ocean has been absorbing more carbon from the atmosphere in recent decades, and find ocean circulation could be responsible.
A team of researchers went back to the same part of Antarctic after a decade to see how the deep ocean had changed, and were surprised to find the deep ocean was fresher than they expected.
The Antarctic Circumpolar current, which wraps around Antarctica and connects the Atlantic, Indian and Pacific Oceans, is notoriously difficult to measure. Recently a group of researchers tackled the wild current, and found it was 30% stronger than scientists previously thought.
A warm blob at the ocean surface, fishery closures, and unhappy marine mammals – what do all these things have in common? The answer is microscopic: a toxic type of algae called Pseudo-nitzschia thrives when temperatures are warm and nutrients are plentiful. It poisons the shellfish that feed marine mammals and support a multi-million dollar fishing industry.
Wanted: Antarctic researchers to study the formation of deep water in the coastal Antarctic seas. Job requirements: Plenty of blubber and a healthy appetite for bottom-dwelling sea creatures.
The ocean is teeming with floating objects. Some of them are creepy, rusted, abandoned boats. Others are cute little bath toys. All are nerdy Halloween costumes waiting to happen! Not to mention their utility as oceanographic tools to learn about currents.
The first things we learn about the ocean are that it’s big and salty. We know that its bigness is an important factor for earth’s climate; the authors of this paper demonstrate that its saltiness is too, and that this can affect whether other earth-like planets are truly habitable.
Paper: Claus W. Böning, et al. 2016. Emerging impact of Greenland meltwater on deepwater formation in the North Atlantic Ocean. Nature Geoscience, v.9: 523–527. We know the ocean is warming due to climate change. But did you also know there are huge paths that heat and energy takes through the global ocean? Although the ocean […]
Scientists investigate warm water that drives melting in Antarctica with the help of some seals with high-tech hats.
A group of scientists have delved deeper to solve the puzzle of why the ocean around Antarctica has been cooling, while the rest of the ocean is rapidly warming.
Glacial runoff, precipitation, and sea ice melt all contribute to the freshwater content of the upper ocean along the west Antarctic Peninsula. Using oxygen isotope samples from water found in different areas of the continental shelf, researchers were able map the areas where different sources of freshwater are more important.
A pair of scientists have figured out how to track deep ocean currents using gravity measurements from space.
New technology lets researchers track the 3D motion of penguins in the ocean to learn exactly where they catch their food. They catch the most when water is cooler than average, which could become a problem as ocean temperatures warm.
Get ready for summer! Scientists have found a new way to predict the extremely hot days that occur throughout summer, using rainfall over land and the temperature of the Pacific Ocean. Read on to learn more!
A classic climate “Whodunit”? Can researchers get to the bottom of the mystery of the cooling eastern Pacific Ocean, three decades in the making?
Hurricane prediction models are constantly improving as we create more innovative ways to study the growth and development of storms. In 2011, a team from Rutgers University sent an autonomous underwater vehicle into the projected path of Hurricane Irene to measure ocean conditions before, during, and after it passed.
Using underwater gliders, researchers explain what caused the extremely warm ocean along the coast of California in 2014-2015 and what this might mean for local ecosystems.
Things heat up as scientists investigate deeper to find out how much heat the ocean can take.
The system of currents that moves water and heat around the globe and regulates global climate may be slowing down. For the first time, researchers are able to track the changes from space.
