#AI at #Sea: #OregonState Sets Sail to Study the #Ocean in Real Time
The lab studies the foundation of the #marine #foodweb by capturing high-resolution imagery and environmental telemetry, then turning those streams into insights. That work is not abstract. It is field #science that depends on ships, sensors, and time windows that cannot be recreated. Losing data is not an inconvenience. It is the loss of a moment in the ocean that will never return.

If you're into #ecology, #metacommunity, #network and #diversity #theory, #foodweb models with #dynamic #traits, #ecoevo #feedback, #complexsystems, or perhaps even #Turingpatterns, my first paper just published in Oikos might be worth a look:
"Metacommunity connectance and emergent patterns drive diversity via spatial eco-evolutionary feedback"

#Oceans just hit an ominous milestone
A new report sounds alarm on #oceanacidification as #Earth breaches the seventh of nine "#planetaryboundaries."
Relentless #acidification of the #seas that’s crossed into dangerous territory, threatening all manner of #marine life, including the organisms at the base of the #foodweb.
#Climate is changing rapidly; #humans are using too much #freshwater; we’re driving species to #extinction and transforming the #biosphere

Warming seas threaten key #phytoplankton species that fuels the #foodweb, study finds
“These are #keystonespecies — very important ones,” said François Ribalet, a research associate professor at the University of Washington’s School of #Oceanography and the study’s lead author. “And when a keystone species decreases in abundance, it always has consequences on #ecology and #biodiversity. The food web is going to change.”

Sinking in Saltwater: #Maine’s #coastal #marshes at risk as sea levels rise
Between 28 and 57 percent of the state’s coastal marshes could disappear by the end of the century, victims of a rising sea, coastal #development and #PollutedRunoff.

July 28, 2024PORTLAND — "It takes hundreds of years for a #SaltMarsh to form, for fine sediment brought in on the tides to settle in sections of shoreline sheltered from the worst of the wind and waves. As salt-tolerant plants — smooth #cordgrass, #SaltmarshHay, #saltgrass, #BlackRush — begin to grow, their dense stems and roots trap more sediment, and the marsh builds more rapidly, up and out.
"#Crabs, #shrimp and #worms arrive, drawn to the rich food of dying marsh grasses, followed by a variety of #fish — #alewives, #StripedBass, #smelt and Sea-run #BrookTrout among them — many of which eventually migrate between the marsh and the sea.
logo for the sinking in saltwater series"Acre by acre, a healthy salt marsh anchors a #FoodWeb 'more productive than most midwestern #farmland,' according to a 2003 paper published by the University of Maine.
"The same dense grasses that are so good at trapping silt also excel at ensnaring pollutants, pulling out nitrogen and nutrients that cause #AlgalBlooms, and burying #toxic #contaminants in the peat.
"Once established, plants in salt marshes grow quickly, fed by the rich soil, and pull #carbon from the atmosphere. Salt marshes are ten times more effective at storing carbon than tropical forests, and, left undisturbed, can trap the gas in the ground for centuries, a phenomenon scientists refer to as 'blue carbon.'
"Maine has some of the most extensive blue carbon reservoirs in the northeast — second only to Massachusetts, according to a study published by the Environmental Protection Agency in 2023.
"But as sea levels rise and development presses in, these reservoirs, and the habitats they create, are at risk of disappearing.
"An analysis by the University of Maine suggests that a significant portion of the Maine’s salt marshes — between 28 and 57 percent, depending on the sea level rise scenario — could be gone by the end of the century. They are also threatened by polluted runoff from #pesticides, #septic systems and #AgriculturalWaste.
"'The decisions Mainers make over the next 10 years are going to determine whether these important ecosystems persist,' said Bates professor Beverly Johnson, who has been studying blue carbon for years, speaking to The #MaineClimateCouncil in December.
"Over the past 25 years, nearly 300 acres of Maine’s wetlands — both fresh and saltwater — have been impacted by or lost to development, according to a Press Herald/Maine Monitor analysis of data from the state’s In Lieu Fee Compensation Program. The program allows developers to fill or convert certain #wetlands if they pay a fee, money that is used for conservation projects elsewhere."

#Pacific coast #graywhales have gotten 13% shorter in the past 20–30 years, study finds
The smaller size could have major consequences for the health and reproductive success of the affected #whales, and also raises alarm bells about the state of the #foodweb in which they coexist, researchers say. If the same trend were to happen in humans, that would be like the height of the average American woman shrinking from 5tf 4in, to 4ft 8in tall over the course of 20 years!

This #EarthDay, here's a reminder that environmentalism without class struggle is just gardening*.
*Nothing against gardening, but we're currently facing global ecological collapse within our lifetimes.

Ocean spray emits more PFAS than industrial polluters
"Stockholm researchers several years ago found that PFAS from ocean waves crashing are released into the air around shorelines, then can travel thousands of kilometers through the atmosphere before the chemicals return to land."
“We thought PFAS were going to go into the ocean and would disappear, but they cycle around and come back to land, and this could continue for a long time into the future."

In the #US, 100% useless and very #climate-destructive #lawn #grass consumes more #acreage than #food #crops.
This ongoing series of one person's #rewilding of their yard is small-scale Everything, Everywhere, All at Once.
"...the #FoodWeb is an #EnergyWeb...bugs which eat plants are a main contributor to this conversion."
"Don't think you have to do a ton of rewilding, just start small."

"With climbing atmospheric CO2, huge amounts of this gas are absorbed by the #oceans, making the waters more and more acidic. This affects a huge number of marine animals and plants alike, but its impact on fleshy #seaweeds around the coast may have knock-on effects across the #FoodWeb, and make our #beaches much less pleasant
The only way to prevent this #acidification of the oceans is to stop releasing so much CO2 into the air, the experts say."

The #alga #Melosiraarctica, which grows under #ArcticSea ice, contains ten times as many #microplastic particles as the surrounding #seawater. This concentration at the base of the #foodweb poses a threat to creatures that feed on the algae at the sea surface. Clumps of #deadalgae also transport the #plastic with its #pollutants particularly quickly into the #dee sea & explains high #microplastic #concentrations in the #sediment there. https://phys.org/news/2023-04-arctic-ice-algae-heavily-contaminated.html
