Anthropogenic stressors can alter the structure and functioning of infaunal communities, which are key drivers of the carbon cycle in marine soft sediments. Nonetheless, the compounded effects of anthropogenic stressors on carbon fluxes in soft benthic systems remain largely unknown. Here, we investigated the cumulative effects of ocean acidification (OA) and hypoxia on the organic […]
The National Oceanic and Atmospheric Administration (NOAA) and the Pacific Islands Ocean Observing System (PacIOOS) at the University of Hawaiʻi at Mānoa, in collaboration with other partners, recently deployed a new ocean acidification (OA) monitoring site in Fagatele Bay National Marine Sanctuary, American Samoa. Derek Manzello, a coral ecologist with NOAA’s Atlantic Oceanographic and Meteorological […]
The levels of acidity in the ocean could increase by 116 percent if carbon emissions aren’t drastically reduced, according to a new report. The report, released by Forest and Bird, showed increased levels of acidity could have a significant impact on the oceans’ ecosystems. Worldwide, oceans absorb 93 percent of the heat in the atmosphere […]
Greenhouse gas emissions could double the acidity of New Zealand’s oceans within 80 years, damaging sea life and the fishing industry, says a new report by Forest & Bird. The report states that the acidity of the seas around Aotearoa has increased by 26 percent since pre-industrial times and could increase by 116 percent by the […]
New Zealand is playing an important leadership role within the Commonwealth in helping counter ocean acidification, Prof Cliff Law says. He is a Wellington-based principal scientist, marine biogeochemistry, and leads the Ocean-Climate Interaction Group at Niwa. He yesterday gave a public talk on ”The Oceans and Climate Change” at the Otago Museum and said public […]
