Have you ever wondered what may live inside the tiniest drops of seawater? Global oceans are dominated by organisms we cannot even see. Marine microbes are resilient, incredibly diverse, and ecologically important. These microbes deserve a closer look.
Clams along the northeastern coast of North America are suffering from a form of cancer that researchers have recently discovered is a new type of contagious cancer.
Many fish utilize different habitats as adults than they do as juveniles, but little research has shown how they make the shift between the two habitats. This recent study did just that using acoustic tags! Read to learn more!
Bad environmental news can seem overwhelming at times. No matter how environmentally aware you are, you will still need to eat something and you will take up space that probably used to belong more to nature than it does now. So let’s take a moment to appreciate why it’s worth trying to conserve nature. Let’s talk about sperm whales pursuing squid in the deep oceans!
Dusky dottybacks are small (8cm/3in) fish found on the Great Barrier reef, but despite their small size, they are fish eating predators feasting on up to 30 juvenile damselfish per day. Dottybacks are able to be so successful at capturing their prey by being masters of deception thanks to their “phenotypic plasticity.”
El Niño/Southern Oscillation (ENSO) can change winter weather on the western coasts of South and North America. Its arm of influence extends to the interior of the US as well, and can affect the frequency of severe weather events such as hailstorms and tornadoes throughout winter and spring.
The ability of sea urchins to withstand ocean acidification comes at a hidden cost.
Sluggish ocean circulation can’t keep up with global climate change and this has caused the North Atlantic to cool.
Aerial photographs are a great way to collect images of marine species in order to analyze their distribution patterns. Distinguishing different species is difficult, and unfortunately this leads to the misidentifictation of several species. This is the case for ice-associated seals, species for which global climate change has motivated intensive monitoring efforts in recent years.
While anthropogenic noise pollution has been gaining a lot of attention, there is still much to be learned about ambient ocean noise. A team of researchers found that glaciers create some of the loudest noises in the ocean, with evolutionary implications for marine organisms living near glaciers. These findings elucidate the nature of ambient, natural ocean noise and helps further our understanding of how additional anthropogenic noise may impact these systems.
Predation by crown of thorns sea stars (COTS) is one of the main causes of coral reef decline in Australia’s Great Barrier Reef. Death by injection of sodium bisulfate is the most commonly used method, but this requires COTS to be removed from the reef and injected many times. Is there a better way? Read more to find out!

Satellite remote sensing suggests that different phytoplankton species can live in harmony during phytoplankton blooms in the open ocean.
Dolphins aren’t always fun loving and gregarious like Flipper. In fact, they often act like bullies. Dolphins show aggression towards other marine species, even their close relatives, porpoises. Off the coast of California, harbor porpoises have had enough, and have started actively avoiding dolphins. Read on to find out more!
Fishery management is complicated, but important. Read more about one way to protect young fish from the Icelandic longline fishery.
When undersea wells blowout, toxic concentrations of hydrocarbons can be rapidly released into the environment. The media presents these blowouts with dramatic images of flora and fauna covered in black tar along coastlines and on the sea surface. What are rarely shown in glossy photographs, however, are the consequences to the unseen deep-sea.
Volatile methyl siloxanes can be easily found in personal care products (e.g. shampoo, lotion and cream) . Recently, scientists detected these compounds in soils, vegetation, phytoplankton, and krill samples from the Antarctic Peninsula region. This finding brings into question the belief that these compounds are not able to reach remote terrestrial and marine surfaces.
Calculating a global average change in sea-level over the twentieth-century is no walk in the park. This study uses a new technique to critically look at previous estimates of sea-level rise. The findings suggest that previous estimates may have been too high, but what does this mean for future sea-level rise projections?
Ever wanted to know what it’s like to go to a scientific conference? Here’s a summary of what conferences are all about, plus the four most interesting talks I saw at this year’s National Shellfisheries Association meeting.
