The oceans’ uptake of anthropogenic carbon dioxide (CO 2 ) decreases seawater pH and alters the inorganic speciation – summarized in term ocean acidification (OA). Already today, coastal regions experience episodic events during which surface layer drops below values projected for at end century. Future OA is expected to further enhance intensity these extreme events. To evaluate influence such regions, we deployed eight pelagic mesocosms 53 days Raunefjord, Norway, enclosed 56–61 m 3 local...
Abstract In certain regions of the predominantly nitrogen limited ocean, microbes can become co-limited by phosphorus. Within such regions, a proportion dissolved organic phosphorus pool be accessed employing variety alkaline phosphatase (APase) enzymes. contrast to PhoA family APases that utilize zinc as cofactor, recent discovery iron cofactor in more widespread PhoX and PhoD implies potential for biochemically dependant interplay between oceanic zinc, cycles. Here we demonstrate enhanced...
Ongoing acidification of the ocean through uptake anthropogenic CO2 is known to affect marine biota and ecosystems with largely unknown consequences for food webs. Changes in web structure have potential alter trophic transfer, partitioning, biogeochemical cycling elements ocean. Here we investigated impact realistic end-of-the-century concentrations on development partitioning carbon, nitrogen, phosphorus, silica pools a coastal pelagic ecosystem (Gullmar Fjord, Sweden). We covered entire...
A Holocene beach ridge and present day shore system located in a rural area north east of Kuala Terengganu was studied. The relation between fecal coliform (FC) MPN Index (Most Probable Number) distribution with rainfalls saline intrusions into the unconfined aquifer ridge–shore examined. probable primary source pollutants also investigated order to highlight susceptibility such aquifers pollution. Six sampling sessions were made from September 2009 January 2010. Three represent drier...
