  1. CW: Study suggests potential health implications of sea spray in coastal areas

    “Living near the ocean, particularly within 5 km, is increasingly linked to public health benefits.

    The air in coastal environments is enriched with sea spray aerosols (SSA) that are generated by wave action and bubble bursting …

    This study provided the first in vitro evidence of potential health benefits caused by SSA and the molecular mechanisms involved.”

  2. Fixing the fishing line

    Sometimes the fishing line gets tangled and you need to stop what you're doing and fix it.

    'When I first became involved in advocating for eastern #tarakihi in 2019, #Fisheries New Zealand’s own #science estimated the eastern stock had fallen to around 16% of its unfished #biomass—well below the 20% soft limit and nowhere near the #Harvest Strategy Standard target of 40%.

    'Six years later, we’re paying substantially more at the checkout, yet the eastern stock remains well under a rebuilding-plan target.
    'Recent projections suggest it is still hovering around the lower management thresholds, with recovery far from assured under current catch settings.
    'That should concern every New Zealander.
    We’ve somehow normalised the idea that a fish can become increasingly expensive while remaining chronically depleted. Consumers are paying more, commercial operators continue #fishing, and we’re repeatedly told the #fishery is being managed “#sustainably”.

    'If this is what #sustainability looks like, perhaps we need to rethink what the word means.

    'A truly #sustainable fishery shouldn’t require decades of rebuilding while the stock remains well below the level our own management system says it should achieve. It shouldn’t leave us debating whether 10–20% of the original spawning biomass is acceptable, and it most certainly shouldn’t have us celebrating modest improvements while remaining nowhere near the target.'
    .....
    'Perhaps the real question isn’t why the price has risen, it’s whether we’ve convinced ourselves that #depletion has become an acceptable definition of sustainability.

  5. 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.

    PORTLAND — "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.

    "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."
