California, Dec 22 (CAnadian-Media): After examining the core samples from the bottom of the Santa Barbara Channel, it was revealed reveal that the waters off the California coast are acidifying twice as fast as the global average, media reports said.
The results of a new study to track the thickness of shells belonging to microscopic animals called foraminifera that had accumulated in Channel sediment over the last 125 years was conducted by National Oceanic and Atmospheric Administration scientists showed California waters experienced a 0.21 decline in pH in that time, more than double the worldwide average of 0.1 pH.

Chemical reaction in the water caused due to increasing amounts of man-made emissions of CO2 absorption by the ocean increase the water’s acidity. Besides causing more frequent and more toxic algae blooms, higher acid levels are fatal to coral and more difficult for organisms like clams and oysters to build their shells.
The study threw an interesting and surprising light on the connection between acidification and a natural warming and cooling cycle called the Pacific Decadal Oscillation.
The scientists pointed out that with the increased amount of ocean acidification due to human-caused CO2 emissions, this natural variation also plays an important role in alleviating or amplifying the trend.
“During the cool phases of the Pacific Decadal Oscillation, strengthened winds across the ocean drive carbon dioxide-rich waters upward toward the surface along the West Coast of the U.S.,” said lead author Emily Osborne in a press statement. “It’s like a double whammy, increasing ocean acidification in this region of the world.”
The study’s findings could have major impacts on the management of some of the most economically valuable fisheries in the country like California crab and shellfish fisheries, the scientists said.
#NovaScotia; #Halifax; #BelugaWhales; #U.S.BasedConservationGroup
Halifax (Nova Scotia), Dec 7 (Canadian-Media): Two prospective sites in rural Nova Scotia for an ocean retirement home for, beluga whales raised in captivity, have been selected by U.S.-based conservation group after their long search for three years, media reports said.
“We are focusing on Nova Scotia for the site for (our) first sanctuary for captive beluga whales,” said Lori Marino, president Whale Sanctuary Project, non-profit group. “There are a couple of sites in Nova Scotia that we have our eye on.”
It was confirmed by the Whale Sanctuary Project Friday that is negotiating with the residents and government officials in the Sheet Harbour and Sherbrooke areas along the province’s rugged and sparsely populated Eastern Shore.
The submission of the final proposal to the regulators or local residents would only be done, after more research and securing community support.
“This is not something you can come in ... and impose on a community,” she said in an interview. “That’s why it’s taken a little bit longer than we anticipated.”
Whales raised in captivity can’t be released into the wild because they don’t have the skills to fend for themselves, said Marine biologist Hal Whitehead, a professor at Dalhousie University in Halifax.

UNCTAD, Dec 6 (Canadian-Media): During the presentation of a draft strategy and an action plan, by the National Focal Points, UNCTAD and DOALOS at the Second National Stakeholders Workshop in December 2019, the related value chains of marine finfish species (not shellfish) and seafood manufacturing were highlighted, UNCTAD reports said.
The objective of the strategy was reaching internal, regional and international markets. The contents of the draft strategy and plan of action were developed based on inputs obtained during the First National Stakeholder Workshop in 2018.
The overall proposed goal of the “Evidence-based and policy coherent oceans economy and trade strategies” project (OETS) report and derived action plan in Belize was to promote the competitiveness and sustainability of the fishing sector, specifically in the sectors related to marine finfish species and seafood manufacturing, while improving the quality of life of people engaged in fishing, and ensuring the sustainability of resources in the long term.
The discussion, review and validation of the OETS report and plan of action was to support, with cooperation of UNCTAD and DOALOS and Commonwealth Secretariat, Belize in the implementation of 1-2 selected priority actions within their areas of competence. All the lessons learned in Belize and in the other beneficiary countries (Costa Rica and Barbados), will be presented in a regional event in 2020, probably during the UNCTAD 15 Conference, to be held in Barbados.
#ASpermWhaleDead; #100KilogramsPlasticTrash; #World'sOceans
Scotland (U.K.), Dec 2 (Canadian-Media): A ball of trash, consisting of nets, bundles of rope, plastic cups, bags, gloves, packing straps and tubing totalled about 100 kilograms heavier than most human beings, was found in the stomach of a dead whale on a beach in Scotland, the Scottish Marine Animal Strandings Scheme reported on its Facebook page Sunday, media reports said.

The animal was too big to be moved, so it was buried on-site.
This is just the latest of several recent reports of whales being found with huge amounts of plastic waste in their stomachs.
This amount of plastic in the stomach demonstrates the hazards that marine litter or discarded fishing gear can cause to marine life.
United Nations Environment Programme reported that the world's oceans now contain an estimated 100 million tonnes of plastic, about 80 to 90 percent of it from land-based sources.
A deal had been reached in May of this year between 180 countries around the world with an aim to reduce the amount of plastic that gets washed into the world's oceans.
