Waters off Scotian Shelf are cooling while scientists wonder if decade-long warming trend is over
In recent years, warming temperatures have grabbed headlines, with record highs being set throughout the region. Recently, on the Scotian shelf, it has moved in the other direction. “It is really interesting,” Beazley said in a wharfside interview at the Bedford Institute of Oceanography. “We did see a continuation of the trend that we observed in 2023, which was the temperatures are actually returning to normal or even below normal conditions in some areas. It’s getting cooler.” Since 2012, ocean temperatures off Nova Scotia at depth have been consistently warmer — by about two degrees above normal. more, >>CLICK TO READ<< 09:29
Atlantic halibut thrive in warming Maritime waters, study finds
Warming ocean temperatures caused by climate change will provide favourable conditions for Atlantic halibut, according to a new study, although what happens to their prey is uncertain. A paper published in the journal FACETS links an exponential increase in Atlantic Canadian landings over the past decade to warming ocean temperatures and predicts that trend is likely to continue under low- and high-warming scenarios in coming decades. “Under both of those scenarios, we see similar trends. Even in the higher emission scenario where it’s warmer, it would appear that halibut stand to gain more habitat with these warming conditions” says co-author Ryan Stanley, a Fisheries and Oceans Canada scientist at the Bedford Institute of Oceanography. more. >>click to read<< 08:46
Claim that Annapolis tidal turbine violates Fisheries Act puts science under review
Is the Annapolis Tidal Generating Station killing a lot of fish? The protesters waving placards on the causeway crossing the Annapolis River on Wednesday and Thursday claim that it does. Scientists and stakeholders meeting over the same period at the Bedford Institute of Oceanography were attempting to answer the same question. But even as The Canadian Science Advisory Secretariat was performing its review of available data, Fisheries and Oceans Canada and Nova Scotia Power may already know whether the turbine is in violation of the Fisheries Act. According to correspondence obtained via a freedom of information request between high level staff at both the federal regulator and the turbine’s owner, both already know it kills fish. >click to read<
DFO scientist amazed by ‘extreme’ ocean temperatures
A federal scientist based in Nova Scotia says ocean temperatures off the East Coast of Canada were about two to four degrees above normal in 2012, setting record highs. “On average, it’s probably three to five times the normal variability. So it’s quite extreme,” said Dave Hebert, a Canadian scientist at the Bedford Institute of Oceanography in Halifax. continued
