In the past few decades scientists have found new and exciting ways to use DNA to answer scientific questions. There is now a new technique that could further revolutionize DNA analysis by using tiny pieces of tissue floating around in the ocean. Read more about how scientists are using this technique to answer questions about whale sharks.
The seafloor is complex and mapping it is difficult because direct observations are hindered because it is underwater. Scientists have developed field methods and remote sensing methods to model the geomorphology of the seafloor but they are either limited spatially or by resolution. A newer method being applied to seafloor mapping is called Structure from Motion, and its low cost and high resolution may play a big role in future projects regarding ocean exploration.

Whales aren’t the only animals hydrophones can detect out in the ocean. In fact, in the near future it might be possible to listen in on animals like scallops and determine if they’re healthy or not. Intrigued? Click here for more!
Scientists may have a new option for figuring out how much debris litters our beaches and what it all is! Find out more in today’s World Oceans Day post on marine debris!
When natural ecosystems are destroyed from anthropogenic development there exists a common notion that a replacement can be replanted somewhere else. One has to wonder though; what if the ecosystem destroyed cannot be replaced into the same role it once had. Scientists investigate if planted mangroves in the Philippines change the natural mangrove areas surrounding the restoration area, and to determine if there are differences in species diversity between planted and natural systems.
You might call it the Batmobile of the sea: Scientists put sound based fish finders into an underwater robot to get closer to the creatures they want to study.
CO2 from fossil fuel burning doesn’t contain C-14. That’s bad news for the future of radiocarbon dating.
There are many steps in the scientific process before a paper is actually published and results are shared with the public. One of the first steps in this process is collecting samples. For a lot of the research discussed here at oceanbites.org, scientists must go out to sea on a research cruise to conduct their science and get those precious samples. Read on for an inside look into how some of this science is actually done at sea!
