Coral reef ecosystems are severely threatened by climate change. The urgent need to address the issue is driving a new era of innovation in reef science, shown by a global multidisciplinary exploration of different approaches to enhance coral resilience.
A study is the first to reveal detailed behavior of massive goliath groupers. Until now, no studies have documented their fine-scale behavior. What is known about them has been learned from divers, underwater video footage, and observing them in captivity. Using a multi-sensor tag with a three axis accelerometer, gyroscope and magnetometer as well as a temperature, pressure and light sensor, a video camera and a hydrophone, researchers show how this species navigates through complex artificial reef environments, maintain themselves in high current areas, and how much time they spend in different cracks and crevices – none of which would be possible without the tag.
The NSF is funding a team led by the Oden Institute for Computational Engineering and Sciences at UT Austin to implement a Deep-Ocean Observing Strategy (iDOOS), bringing together U.S. and international networks engaged in deep-ocean observing, mapping, exploration, modeling, research and sustainable management.
Assemblages of tropical non-indigenous species in the Eastern Mediterranean have biological traits that markedly differ from those of native biological communities. This was shown by an international team of scientists led by Jan Steger from the Department of Palaeontology at the University of Vienna.
We all know that the dinosaurs died in a mass extinction. But did you know that there were other mass extinctions?

Dr. Ramakrishna brings decades of climate work to this newly created position, with a goal of expanding WHOI’s visibility and impact on global ocean and climate policy issues.
A new study shows how changes in light conditions have a significant influence on the growth and impact of harmful algae blooms. The bottom line: a warming climate looks good for the growth of toxic algae and may disrupt other organisms that are part of the food web — whether they graze on this algae or are consumed by it.
The Gulf of Mexico Alliance has released the Governors’ Action Plan IV for Healthy and Resilient Coasts, signed by the governors of all five Gulf states: Alabama, Florida, Louisiana, Mississippi, and Texas. This is the fourth in a series of collaborative work plans that identifies priority issues, focus areas, and actions to enhance the environmental and economic health of the Gulf of Mexico.
In a major development in the bid to deepen the understanding of the role that the ocean plays in climate science, Arizona State University (ASU) President Michael Crow announced today that ASU, a leading research university, has established a partnership with the Bermuda Institute of Ocean Sciences (BIOS), one of the longest-serving research institutes dedicated to studying ocean processes in the Western Hemisphere.
The RUDN University biologist with colleagues from Egypt, Italy, Iran, Canada, Thailand and Turkey summarized research data on the effect of phytonutrients on fish health at the molecular level.

RUDN University veterinarians together with colleagues from Iran, Thailand and Turkey have proved the efficacy of a herbal drug for anesthesia in Nile tilapia. It works no worse than analogues but causes less stress in fish.
A new study from two researchers at the Georgia Institute of Technology provides both hope and a potentially grim future for damaged coral reefs. In their research paper, "Biodiversity has a positive but saturating effect on imperiled coral reefs," published October 13 in Science Advances, Cody Clements and Mark Hay found that increasing coral richness by ‘outplanting’ a diverse group of coral species together improves coral growth and survivorship.

Tulane professor Henry "Hank" Bart is teaming up with researchers across the country as part of a $15 million NSF initiative to establish the inaugural Imageomics Institute.
Turtles from the heavily polluted Indian River Lagoon (IRL) had compromised immune function. Those with tumors (Green Turtle Fibropapillomatosis or GTF) had less immune competence. Habitat quality, disease state, and immune function are intertwined. Polluted environments impact the immune system and make animals more prone to the expression of GTF, which in turn further compromises the immune system. This vicious cycle may explain why some areas have such a high incidence of GTF, while other areas have turtles that test positive for the GTF virus, but are clinically healthy.
New research from the University of Wisconsin–Madison, the National Oceanic and Atmospheric Administration and others significantly alters the prevailing understanding of how marine life influences clouds and may change the way scientists predict how cloud formation responds to changes in the oceans.
Seabirds from Gough Island in the south Atlantic, Marion Island near Antarctica and the coasts of both Hawaii and Western Australia have a dangerous habit: eating plastic.
Marine heatwaves, driven by climate change, are becoming more frequent and intense worldwide.
In a study of crayfish in the Current River in southeastern Missouri, researchers discovered – almost by chance – that the virile crayfish, Faxonius virilis, was interbreeding with a native crayfish, potentially altering the native’s genetics, life history and ecology.
For many marine animals, like the Dungeness crab, seasonality and timing are components of complex life cycles, where disruptions can have serious implications for the population.

Changes in the northern Alaskan Arctic ocean environment have reached a point at which a previously rare phenomenon—widespread blooms of toxic algae—could become more commonplace, potentially threatening a wide range of marine wildlife and the people who rely on local marine resources for food. That is the conclusion of a new study about harmful algal blooms (HABs) of the toxic algae Alexandrium catenella being published in the journal Proceedings of the National Academy of Science.
