Life in the Abyss: the ecological impacts of deep-sea mining
Did you know that about 95% of the ocean is unexplored? The deep ocean is logistically very difficult to access, so how do scientists study organisms that live at 400 meters below the sea surface? The landscape of the deep-sea is diverse and certain structures such as polymetallic nodules, supports a vast array of marine […]

The recovery of marine mammals in North America is a shining conservation success story, but what happens when that success spells doom for at-risk species further down the food chain? This week we’ll dive into how grey seals are impacting winter skates, a northern relative of sharks and rays, in the southern Gulf of St. […]
Life is difficult in the harsh environment of the deep ocean. Crushing pressures and freezing temperatures prevent many animals from surviving in the deepest depths of our oceans. Yet, somehow, a deep-sea amphipod beats all odds and is able to survive and flourish in the deepest parts of the ocean. Scientists have now discovered how […]
Kos Kramar M, Tinta T, Lučić D, Malej A, Turk V (2019) Bacteria associated with moon jellyfish during bloom and post-bloom periods in the Gulf of Trieste (northern Adriatic). PLoS ONE 14(1): e0198056. https://doi.org/10.1371/journal.pone.0198056 Bacteria are ancient single-celled organisms that live on just about every surface on Earth; every patch of soil, every raindrop, doorknob, […]
There are many environmental factors which affect the way marine organisms behave, and temperature is one of those very factors. Yes, temperature can permanently determine whether an organism is male or female.
Great white sharks are at the top of the food web and therefore build up large amounts of toxins like heavy metals in their systems. But does this impact their overall health? Find out in the most recent Sharkbites Saturday post!

Ocean acidification has been known to cause problems for marine mollusks (like oysters and pteropods), because these animals have shells or hard parts that can weaken as acidity increases. There’s another mollusk though with eight arms and two tentacles that may have a larger bag of tricks with which to cope with acidity, but teasing […]
What is so important about those seasonal green swirls in the ocean? In addition from being seen from space, those swirls are phytoplankton blooms that provide food resources for marine ecosystems. Read on to find out what causes these blooms, and how climate warming may alter them.
Article Habitat geography around Hawaii’s oceanic islands influences tiger shark (Galeocerdo cuvier) spatial behavior and shark bite risk at ocean recreation sites. (2018). DOI: 10.1038/s41598-018-23006-0. https://www.nature.com/articles/s41598-018-23006-0 Background The U.S. state of Hawaii is an archipelago of eight major islands, of which Maui is one of the major islands, also considered the second most populated. The island […]
An intense red tide overtook both the east and west coasts of the Sunshine State in 2018, killing fish, manatees, whale sharks, and choking beach tourism in the process. Researchers at the University of south Florida and the Fish and Wildlife Research Institute, led by Dr. Robert Weisberg, set out to discover the origin of […]
Bulkheads and other ‘armored,’ or hardened, shorelines are cheap, easy to install, and effectively prevent erosion and protect private property…. Or do they?
Humans create a lot of noises that seep into natural environments, polluting the natural soundscape. Noise pollution can be harmful for marine life by interrupting migration routes and disrupting normal communication. Now, a new study finds that the man-made noise pollution can even change the way fishes grow!
River dolphins are some of the most endangered dolphin species in the world. Unfortunately, they are vastly understudied and greatly misunderstood. For the first time ever scientists were able to capture hundreds of different calls, showing that these animals have a vast language unique from other species.
The deep sea is a hostile environment – think corrosive seawater and bone-crushing pressures – not to mention underwater volcanoes spewing hot, gassy fluids. Read how scientists explored the most active underwater volcano in the Caribbean Sea using lasers!
Welcome to oceanbites!
The goal of oceanbites is to make cutting edge research in the ocean sciences accessible to all. oceanbites will also highlight classic, seminal research papers, and feature op eds about current issues in research.
