My 25 Favorite Things For Ocean Field Work

I am particular about my set of gear and equipment that I take when I am out at sea. Much time spent was spent on trial and error research and development of my sea kit. The items below reflect advice from my scientific mentors and advice about tools from my father and father-in-law, one an […]

Photos: Oceana in Belize Exposes Belizean Youth to the Wonder of the Sea

Belizean boys on the trip to the Lighthouse Reed Atoll. (Photo: Oceana in Belize / Alexander Ellis / Flickr) Oceana in Belize has been busy instilling a sense of wonder and stewardship for the oceans in Belizean youth. Earlier this month, they took a group of underprovided boys, all under the age of 14, to Belize’s beautiful coast. Show More Summary

Ocean Roundup: Rare Blue Lobster Caught in Maine, Cephalopod Skin Providing Groundwork for New Technology, and More

Common octopus (Octopus vulgaris) in Portugal. Cephalopods, like octopuses, have been inspiration for new technology. (Photo: Oceana / Carlos Minguell) - New York City may seem like the last place to spot whales, but these cetaceans are making a comeback in the area. This summer, an eco-tourism group has spotted 52 whales alone. CBS News read more

Limpets counteract ocean acidification induced shell corrosion by thickening of aragonitic shell layers

Specimens of the patellogastropod limpet Patella caerulea were collected within (pHlow-shells) and outside (pHn-shells) a CO2 vent site at Ischia, Italy. Four pHlow-shells and four pHn-shells were sectioned transversally and scanned for polymorph distribution by means of confocal Raman microscopy. Show More Summary

Interactive effects of ocean acidification and warming on subtidal mussels and sea stars from Atlantic Canada

Anthropogenic CO2 is decreasing oceanic pH and contributing to seawater warming. We tested the effects of low pH and high temperature at levels predicted for 2100 on an ecologically important predator–prey system (sea stars, Asterias rubens, and mussels, Mytilus edulis) from the NW Atlantic coast.

Metabolic suppression during protracted exposure to hypoxia in the jumbo squid, Dosidicus gigas, living in an oxygen minimum zone

The jumbo squid, Dosidicus gigas, can survive extended forays into the oxygen minimum zone (OMZ) of the Eastern Pacific Ocean. Previous studies have demonstrated reduced oxygen consumption and a limited anaerobic contribution to ATP production, suggesting the capacity for substantial metabolic suppression during hypoxic exposure.

No way is that a Manta in the Kelp Forest…

Yes…yes it is.   This video was just taken off of San Clemente Island by spearfisherman Carter Jessop (used with permission). This is his account of the miraculous interaction: “The real excitement of the trip came on the second afternoon at the island. We were diving a spot with strong wind and current and I […]

Action Alert: Grand Canyons of the Bering Sea

  Time Remaining to Take Action: Protect the Bering Sea’s Grand Canyons Background In 2007, Greenpeace launched a groundbreaking expedition to explore the two largest underwater canyons in the world, in the heart of the Bering Sea. It was the first time manned submersibles ever entered these canyons and human eyes gazed directly upon their […]

Chile Cancels September Crustacean Trawl to Protect Common Hake

Hakes (Merluccius sp.) in a crate. (Photo: Oceana / LX) Chile has taken a major step to protect common hake, a species in decline from overfishing. Earlier this month, the Under-Secretariat of Fisheries and Aquaculture (SUBPESCA) decided...Show More Summary

Ocean Roundup: Maine’s Scallop Fishery Could See Closures, Sydney Harbor Littered with Microplastics, and More

Patagonia Scallop (Zygochlamys patagonica). (Photo: Oceana / Eduardo Sorensen) - Maine’s scallop fishery could see multiple closures in the upcoming December season as regulators work to rebuild the fishery. Fishermen caught millions of pounds of scallops from the 1970s to 1990s, but the fishery then dropped dramatically. The Associated Press read more

Living in warmer more acidic oceans retards physiological recovery from tidal emersion in the velvet swimming crab Necora puber (L.)

The distribution patterns of many species in the intertidal zone are partly determined by their ability to survive and recover from tidal emersion. During emersion most crustaceans experience gill-collapse impairing gas-exchange. Such...Show More Summary

Characterization of the Antarctic sea urchin (Sterechinus neumayeri) transcriptome and mitogenome: a molecular resource for phylogenetics, ecophysiology and global change biology

This is the first de novo transcriptome and complete mitochondrial genome of an Antarctic sea urchin species sequenced to date. Sterechinus neumayeri is an Antarctic sea urchin and a model species for ecology, development, physiology, and global change biology. Show More Summary

Health and population-dependent effects of ocean acidification on the marine isopod Idotea balthica

Three populations of the grazing isopod Idotea balthica were exposed to high CO2 treatment for a period of 20 days to investigate the effect of ocean acidification (OA) on animal health and immunocompetence. The results of the populations from more saline habitats were comparable and showed a 60–80 % decrease in immune response as a […]

Long Island Sound becoming more acidic, scientists say

Long Island Sound, already choked with nitrogen, may also be becoming more acidic — a state that could threaten marine life. Scientists are turning their attention to the phenomenon of ocean acidification — and its potential impact on the hard clams, oysters and other shellfish that make the Sound their home. Acidic water could threaten […]

Oceana Magazine: Tuna in Trouble

Now, seismic airgun testing in the Mediterranean Sea threatens to unravel progress that was made for this super predator. Show More Summary

Leanna’s Release!

After just over two months in rehabilitation, Leanna, an adult Hawksbill was returned to the wild. She was originally found off of Pumpkin Key in early June, severely entangled in a rope attached to a heavy cement crab trap. Her flipper was so badly damaged that it needed to be amputated at The Turtle Hospital by Dr. Cathy of MVH. Her wound healed nicely and … Read More ?

Seaweed Spotlight: A Rare Glimpse into Beautiful Ocean Kelp Forests (Photos)

(Photo: Oceana / Juan Carlos Calvin) Forest ecosystems are critical for the survival of terrestrial life, but did you know that such ecosystems exist in the oceans too? Kelp, a type of seaweed, can form dense forests underwater. Show More Summary
