Hidden fish populations protect us from ourselves!

We raise cows, chickens, and pigs on farms, but we still commonly hunt wild populations for one type of animal protein- seafood. Many fish populations are overexploited, but scientists found that despite this, Atlantic flounder populations were in better shape than expected. Why? How can we ensure that this stability continues?

It’s Not Just About Fish: How Understanding Ecosystem Services Can Lead to Marine Conservation

What is the value of a fish? It’s role in the ecosystem, or the community that relies on the species? A team of scientists from the UK explores these interactions in their recent paper, which details the use of ecosystem services in marine conservation.

The Five Deeps Expedition: The first attempt to dive to the deepest point in five oceans

The Five Deeps Expedition is led by Victor Vescovo, an American attempting to visit the five deepest areas of the ocean in a manned submersible. In December of 2018, he became the first human to reach the bottom of the Puerto Rico Trench in the Atlantic Ocean. Read on to learn more about this expedition, and keep an eye out for the results of the remaining four dives in 2019!

Flame retardant sharks?

Flame retardants are found everywhere from your house to your car. Unfortunately, these chemicals can accumulate in the environment, including the ocean. Once in the ocean, flame retardants can make their way into marine organisms. The researchers in this study wanted to determine if flame retardants are transferred from mothers to offspring in sharks.

Desalination: As If Corals Didn’t Have Enough to Worry About Already

Clean, safe drinking water is a basic human need. However, for many areas around the globe, freshwater is becoming scarce. Desalination is increasingly used to provide drinking water in some coastal regions, but the waste products – brine and antiscalants – are discharged back into the ocean with unknown consequences. A recent study by Karen Lykkebo Petersen (University of California Santa Cruz) and colleagues sought to simulate happens to coral reefs as they are increasingly exposed to desalination discharge.

Diving deep: benefits of deep sea coral refuges in the Atlantic

Take a dive into the fascinating world of deep sea coral reefs off the South Atlantic Coast and their role in supporting diverse reef fish communities. The paper examines the differences between shallow and deep reefs and explores why they may require distinctions when setting management goals.

More than just a coincidence? What the co-occurrence of species can teach us about how they interact

Different kinds of plants, animals, and fungi interact with each other in a myriad of ways.  Recently, researchers have been trying to infer the nature of these interactions just by looking at whether you can find these species in the same place!  In a 2018 study, Mara Freilich of the Massachusetts Institute of Technology and her co-authors examined the reliability of this co-occurrence approach.

Cropland nitrogen allocation – A deeper dive into the stressors impacting the oceans

Around the globe, 40-50% of the nitrogen applied to cropland in fertilizers remains in the environment. Excess nitrogen is an important environmental stressor that degrades water, air and soil quality and enhances coastal eutrophication. Efficiently allocating nitrogen across space both maximizes crop yields and minimizes excess nitrogen losses to the environment.
