  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.”

    “Permafrost soils are particularly vulnerable to climate change. To assess and improve estimations of carbon (C) and nitrogen (N) budgets it is necessary to accurately map soil carbon and nitrogen in the permafrost region. In particular, soil organic carbon (SOC) stocks have been predicted and mapped by many studies from local to pan-Arctic scales. Several studies have been carried out at the Canadian Beaufort Sea coast, though no regional maps of terrestrial carbon stocks based on spatial modelling has been conducted yet. This study combines available field data from the Canadian Yukon coastal plain and uses it to map regional SOC and N stocks using the machine learning algorithm random forest and environmental variables based on remote sensing data. [The authors] developed models using the data for the entire region and separate models for the coastal mainland area and Qikiqtaruk Herschel Island. Each model was used to map SOC and N stocks for its respective area. [They] assessed the performance of the different random forest models by using crossvalidation. [They] further assessed model results using the Area of Applicability (AOA) method and the quantile regression forest approach, comparing the results and discussing their implications within the context of both methods. [They] explore[d] local differences in soil properties and how soil data distribution across the region affects the accuracy of the predictions of SOC and N stocks..."

  3. Fixing the fishing line

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

  4. Casting Off the Pier

  5. Casting Off the Pier

    Two anglers cast off the end of Ballycotton pier as the sun set. The harbour crane stood black against the sky, and one man's rod bent back mid-cast, blurred by the long exposure. The cloud broke into pink and orange over the headland to the west, with the houses along the shore already lit. It was a warm, still August evening.

    '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.

    [this paper is WAY over my head in terms of the nuance of structural geology, but still fascinating; further, I have to say: these are TRULY gorgeous, well-designed & presented, and useful geologic maps, cross-sections, annotated photographs and other visualisations (I am jealous of that level of skill, in the BEST of ways!)]

  10. The impacts of fossil fuel emissions are gnawing on Australia's coastline

    "Australia's exposure to current and future risks from the sea, including coastal erosion, king tides and rising sea levels, was "very high", The Insurance Council of Australia.

    "Sea level rise caused by climate change would mean the issue was not going away, and Australians needed to consider what we valued about our coastline."

    "Why a seawall might not protect both beaches and homes from coastal erosion...We'll end up with a giant wall around our beaches, or around our whole coastline. That's not saving the landscape, that's saving the infrastructure. We've got to slow down development and look at what we value about the beach."

    Professor Kennedy "said governments would need to consider buying back beachfront land and rehabilitating it, to protect both infrastructure and the beach."

  11. On #WorldOceanDay, new co-authored paper that calls for rethinking development in coastal zones, away from extractive models and toward approaches that respect local knowledge, ecological interdependence, and justice.
    As climate change threatens our coasts, we must listen to and amplify the voices of communities who have long lived in harmony with the ocean
