    “NOAA has upgraded its tidal datum calculation tool with new integrated features! [links above] Did you know you can use this resource to perform your own tidal datum computations and understand local flood frequency?
    The Tidal Datum Analysis Calculator is available now for users to input their data to help make informed decisions on tidal flooding, coastal inundation, and other critical coastal issues.
    With the National Tidal Datum Epoch release rescheduled for 2029, this tool serves as a resource for stakeholders to analyze and understand water level data in their areas of interest by calculating preliminary datums relative to the new epoch…”

  3. 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..."

  5. Fixing the fishing line

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

  7. Last Light at Ballycotton

    The three of them had the pier to themselves, rods out over water that had gone completely flat. I was there with Blarney Photography Club, and sunset is always an attraction there. It had already happened somewhere behind the headland, leaving a band of yellow along the horizon and nothing else lit. Not one of them turned to look at it. They watched the water instead, which is important if you have come to catch something.

  9. 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."
