Microplastics Ingested in the Deep-Sea

Published 2016-10-04

Photo: Michelle Taylor A unique collaboration between scientific researchers at the University of Oxford, University of Bristol, National History Museum in London, and Staffordshire University’s Department of Forensic and Crime Science recently led to the discovery of microplastics in ingested material from deep-sea creatures. Microplastics are plastic particles under 5mm in length and are found in cosmetics, cleaning materials, and other common household products. They can be in the form of small beads or microfibers composed of polyester, nylon and acrylic. The UK government recently... (more)

Launch for New Reef Restoration Initiative

Published 2016-09-20

Photo: Nature Conservancy On September 12, 2016, the Mote Marine Laboratory and The Nature Conservancy signed a one-year memorandum of understanding initiating the first steps of a 15-year partnership to restore and conserve coral reefs at an unprecedented scale. The goal of this collaboration is to restore over one million corals across Florida and Caribbean reefs while building conservation solutions with multiple partners and setting up the infrastructure for coral gene banks. Mote Marine Laboratory, located Florida, is an independent nonprofit marine science and education... (more)

Expanding the Papahanaumokuakea Monument

Published 2016-08-31

The Northwestern Hawaiian Islands of the Papahanaumokuakea Marine National Monument (PMNM) are home to some of the world’s most northern and healthy coral reef ecosystems. Blue whales, albatross, Hawaiian monk seals, turtles, and the oldest living animals on Earth, black corals, are all found in these Pacific waters. Many of the organisms found on the reefs, seamounts, and sunken islands of the PMNM are found nowhere else in the world, with many remaining to be discovered. You can read more about one of these newly discovered creatures, the white octopus called Casper, here:... (more)

A new microscopic view of the marine world

Published 2016-08-02

Researchers at the Scripps Institute of Oceanography at the University of San Diego are changing the way marine scientists can use microscopes to study life in the ocean. The team of researchers have successfully developed an underwater microscope (the Benthic Underwater Microscope, or BUM) that can observe marine organisms in their natural habitat at the scale of nearly one micron resolution. At this scale, the BUM is capable of imaging single cells underwater. To do this, it is built as a two-part system including a computer with a diver interface connected to an imaging unit. The imaging... (more)

A complex story for deep-water corals

Published 2016-07-12

Photo: NOC Eight years after the establishment of a Marine Protected Area (MPA) off North West Scotland in the Rockall Trough, scientists have found a complex story for deep-sea coral reefs. Deep sea corals are different from their tropical counterparts in that they do not form a symbiotic relationship with dinoflaggelate algae, and can therefore survive in colder, deeper, and darker waters. Similar to tropical reefs, cold-water corals provide habitat for many other organisms, including commercially important fish species. Unfortunately, this means that cold-water corals are often in areas... (more)

The 3rd hot year for corals

Published 2016-06-28

The National Oceanic and Atmospheric Administration is advising the public, scientists, and ocean resource managers to be on watch for a 3rd consecutive coral bleaching event this year. The NOAA Coral Reef Watch program predicts that there is a 90 percent chance of a widespread coral bleaching occurring once again during a probable the La Nina cycle. The combined effects of climate change and an intense El Nino cycle led to an increase in sea surface temperatures and triggered coral bleaching starting in mid-2014. Since then, 70 percent of United States coral reefs, for example, have... (more)

Coral spawning triggered by temperature

Published 2016-05-31

Photo: Australian Geographic As summer approaches in the northern hemisphere, coral colonies of certain species are preparing for mass spawning events, in which coral parents synchronously release egg and sperm into the water to be fertilized. Following fertilization, the embryos develop into swimming larvae, which will seek a suitable substrate upon which to settle and metamorphose into a polyp. During these mass spawning events, timing of release of egg and sperm by coral colonies on a reef is key. Scientists are still perplexed by the processes that trigger spawning release in... (more)

Largest biomass of sharks in the Galapagos

Published 2016-05-17

The Galapagos Islands were made famous by Charles Darwin’s expeditions and explorations of the islands’ flora and fauna. Today, the terrestrial and marine ecosystems of these islands are still a source of inspiration and curiosity for scientists. Recently, scientists from the Charles Darwin Research Station and National Geographic reported that the Darwin and Wolf Islands of the Galapagos are home to the world’s largest biomass of sharks at 12.4 tons per hectare. This assessment puts the biomass of sharks in the Galapagos above that at Costa Rica’s Cocos Island National Park and the... (more)

Explore the Mariana Trench with Okeanos

Published 2016-05-03

Scientists, engineers, and technicians aboard the NOAA Okeanos Explorer began a journey in 2016 to map and explore deep and remote areas of the oceans surrounding the Hawaiian Archipelago, the Commonwealth of the Northern Marianas Islands, Wake Atoll, and the Marianas Trench National Monument. The 2016 field season for the Okeanos Explorer marks the second year of the Campaign to Address Pacific Monument Science, Technology, and Ocean Needs (CAPSTONE). The purpose of this campaign is to collect baseline biological, geological, and oceanographic information to support science and management of... (more)

Coral bleaching in a global index

Published 2016-04-19

In a world of growing scientific knowledge and an explosion of data, it is a difficult task to synthesize a high number of studies to make conclusions that drive political, management, and research decisions. In the field of coral reef science, the literature on coral bleaching and the susceptibility of corals to thermal stress is rapidly expanding. In an attempt to gather and group this information for coral reef conservation, Swain and colleagues (2016) have conducted a major meta-analysis of the coral bleaching data currently available and created a “global index” of the most sensitive...
