Drivers of CO2-carbonate system variability in the coastal ocean south of Honolulu, Hawai’i

Frontiers in Marine Science
This study examines carbonate chemistry variability from 2008 to 2021 in subtropical coastal waters adjacent to Honolulu, Hawai’i. We use surface seawater carbon dioxide partial pressure (pCO2sw) measurements obtained every three hours from two buoys ...

Evaluating the protection status and exposure to warming of Caribbean reefs with high functional potential

Conservation Biology, EarlyView.
Abstract Over the past decades, climate change has emerged as a major threat to global biodiversity, negatively affecting the integrity and functioning of ecosystems and the benefits they provide to people. To mitigate these impacts, it is essential to identify climate refugia that support the persistence of the structure and function of reef ...

Resilience of Atlantic Slippersnail Crepidula fornicata Larvae in the Face of Severe Coastal Acidification

Frontiers in Marine Science, 2018
Globally, average oceanic pH is dropping, and it will continue to decline into the foreseeable future. This ocean acidification (OA) will exacerbate the natural fluctuations in pH that nearshore ecosystems currently experience daily, potentially pushing ...

Climate Vulnerability of Australian Seafood Systems: A National Assessment of Exposure and Adaptive Capacity

Fisheries Oceanography, EarlyView.
ABSTRACT Marine waters are becoming warmer and acidified and experiencing more intense and longer heatwaves under climate change. These changes are already impacting marine ecosystems and seafood production, which are vital for supporting food security and economic productivity.

Integrative taxonomy of Harveylithon (Corallinales, Rhodophyta) reveals three new species from Korea and expanded diversity in the northwestern Pacific

Journal of Phycology, EarlyView.
Abstract Non‐geniculate coralline genus Harveylithon includes 12 species worldwide. In this study, we propose three new species, Ha. koreanum sp. nov., Ha. longiforme sp. nov., and Ha. planiforme sp. nov., based on integrative molecular and morphological analyses.

The Greenland–Scotland Ridge in a Changing Ocean: Time to Act?

Marine Ecology, EarlyView.
ABSTRACT The Greenland–Scotland Ridge is a submarine mountain that rises up to 500 m below the sea surface and extends from the east coast of Greenland to the continental shelf of Iceland and across the Faroe Islands to Scotland. The ridge not only separates deeper ocean basins on either side, that is, the North Atlantic and Arctic oceans, but also ...
