Back in January, one of PME’s miniDOT loggers survived a flash flood. This little instrument was swept up in a debris flow and reappeared 250 meters downstream with all its data and its body (mostly) intact.
A study found ocean oxygen content worldwide dropped more than 2 percent from 1960 to 2010. It’s a long-predicted result of climate change, caused by warmer oceans and less circulation.
The world’s coral reefs, already bleached and stressed by increasing CO2, could be destroyed by “weed-like” algae by 2100 under a scenario of continuing greenhouse gas emissions, a study warns.
The miniDOT, our submersible dissolved oxygen and temperature logger, is available to demo! Click below if you are interested in one of our miniDOT loaners for freshwater, brackish, or saltwater monitoring.
GULF SHRIMP PRICE FLUCTUATIONS SHOW EFFECTS OF DEAD ZONES
A Duke University study shows a link between the hypoxic zones off the Gulf of Mexico and the price disparity of large and small shrimp, as fishermen change behavior based on the environment.
OCEAN ACIDIFICATION COULD HIT DUNGENESS CRAB FISHERY HARDEST
As ocean carbon dioxide levels rise, declines in the $220 million Dungeness crab industry will likely be the biggest economic impact on U.S. West Coast fisheries, according to a NOAA study.
SEA LICE THREATEN SALMON FARMS AND CONSUMER CONFIDENCE
Sea lice have decimated some salmon farms in Europe. Even though sea lice and algae blooms are not a big threat in the wild, negative news coverage reduces demand for all salmon, farmed or wild.
PME CEO Kristin Elliott, who received her MBA at Cal State San Marcos College of Business Administration, has been invited to participate in the college’s Meet the Leaders program, where she will share insights with CSUSM business students.
As seen in California this winter, high water flows erode sediment, which can clog the gills of young salmon, or cover up eggs. Biologists are also concerned how floods can disrupt ecosystems.
Researchers have identified phenanthrene as the chemical in petroleum that kills fish by disrupting heart cell function. This chemical is also present in runoff and in the atmosphere.
ATMOSPHERIC STILLING LINKED TO THERMAL STRATIFICATION
Researchers used miniDOT loggers to record temperatures in a European lake over the course of two years to better understand how declining wind speed affects lake temperature gradients.
MiniDOTs were employed to log temperatures and dissolved oxygen in this study of the health of Tathlina Lake’s whitefish and walleye, two species important for local Native Americans.
