Yes, you can purchase a fuzzy red tide-forming algal cell. Aside from being much smaller and lacking any type of eye, these organisms can produce massive, toxin-rich blooms in the ocean. Nasty toxins can be harmful to other organisms in the water and even reach humans via the consumption of shellfish and fish. Through the release of chemical cues, copepods have been shown to promote further toxicity in bloom-forming algae.
Fish are cold blooded, right? Their body temperature is regulated by the temperature of the surrounding water. Well, this may not be the case for all fish. New evidence suggests a species of fish, the opah, is warm blooded! This is the first evidence of full body endothermy in fishes, making this fish kind of a big deal
A technology that both benefits fishermen and helps prevent sea turtle bycatch? Yes, please! The great news is that it exists! And now, it has been updated to include leatherbacks. Read on to learn more about TurtleWatch.
The first seafloor massive sulfide mine in the Pacific is expected to begin commercial operation in 2017. Licenses have already been granted and environmental impact assessments conducted, but we know little about the marine communities surrounding sulfide deposits in the ocean. This study characterizes such communities in a future mining exploration site.
Marine sediments are responsible for long-term burial of organic carbon. Fjords transport massive amounts of fresh sediment to the ocean each year, and researchers created new organic carbon burial budgets to account for this. They have found that 18 Megatons of organic carbon are buried in these environments each year, which further demonstrates the importance of high-latitude glacial systems.
Scientists think they’ve found an ancient link to the eukaryotic cell from the deep down in the ocean, and it’s an archaeon.
New light has been shed on the possibility of an alternative iron sink than previous thought prior to the oxygenation of the oceans 2.45 billion years ago. The findings could affect our interpretations of the early seawater chemistry, nutrient cycling, and trace metal distribution in the Precambrian.
River herring are anadromous fish, which means they live most of their life in the ocean but spawn in freshwater streams and rivers. Recent decades have seen a massive decline in river herring populations caused primarily by over-harvesting and decreased access to spawning habitat. These fish are now largely protected in freshwater systems during their spawning migrations, but they are still at risk of bycatch while in the ocean. Little is known about river herring movement behavior while they are in the ocean. Cutting edge technology in chemistry and genetics is helping to shed light on this.
An illusional and fanciful pause in global warming has climate change skeptic buzzing. Understanding the decadal oscillations of natural climate variability places transient pauses in global warming in perspective. Spoiler: we’re still trending towards a warmer climate.
One would think that an isolated reef ecosystem shielded from the influence of people would provide an ideal benchmark against which other coral reefs can be compared. But in a recent study, researchers found it isn’t that simple.
A team of researchers have discovered extremely elastic nerves in the mouth and tongue of rorqual whales. This is highly unusual considering nerves in nearly all other animals are quite rigid and sensitive to damage by overextension.
Photo ID databases have been used to estimate population sizes for zebras, cheetahs, whales, sharks dolphins, turtles and more. This tool has now spread to a new area. Introducing the first animal photo ID database in Taiwan for green sea turtles!
The Massachusetts Water Resources Authority spent ten years from 1991 and 2000 drastically improving the treatment of waste water released into Boston Harbor in an effort to improve the overall health of this unique estuary. This study measured how the sediments reacted and recovered to this massive effort. Despite the complexities and variability, from start to finish the sediments saw reductions in oxygen demand, nitrogen fluxes, and organic matter.
For an apex marine predator like bluefin tuna, increased abundance of prey species should be beneficial. So why then is tuna health on the decline? Read on to find out!
The relationship between sea urchin, their amoeba pathogens and their kelp prey is changing with the climate. Find out how!
Many of us believe that the deep ocean is pristine and not affected by any human activities; the fact that pollutants such as perfluoroalkyl substances can reach deep ocean gives us a warning sign. It was estimated that around 60 kg of these chemicals was transported during the sampling periods.
Researchers in Australia investigated whether sea urchin sperm are going to make it through an acidified ocean or if they’ve reached their tipping point. Read on to learn more!
Two hot items in climate science today are the North American drought and the decade-long warming hiatus. This study finds a relationship between these two headliners and seeks to answer the question: Are humans responsible for the drought?
Damselfish offspring inherit a trait developed by parents raised in warmer temperatures.
The Mediterranean seagrass plays very important ecological functions but human disturbances are thought to be one of the main causes for its population decline. In this study, Jahnke et al (2015) try to understand how genetic diversity correlates with human disturbances and the results are surprising.
