  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. Beyond The 100-Year Flood - Probabilistic Flood Hazard Assessment For King And Pierce Counties Under Future Climate Scenarios

    “Flood maps are usually built from a single design storm. For King and Pierce Counties in the Pacific Northwest (USA), [the authors] tried the opposite - simulate 82 years of actual coastal and river conditions (plus 18 synthetic years) with SFINCS and let the statistics fall out cell by cell. That took about 5,400 yearly simulations and 194,000 CPU hours on USGS's Hovenweep HPC. Worth it!
    The design-event shortcut turns out to hide a real hazard. A deterministic 10-year event underestimated flood depths by up to half a meter compared to the continuous runs.
    The bigger surprise [to the authors] was how one-sided the climate signal is. One metre of sea level rise takes King County's expected annual flooded area from 161 --> 787 hectares, almost a factor of five. Changes in storminess over the same horizon barely register. And somewhere between 100 and 150 cm of SLR, land that never floods today starts flooding fast. If you plan adaptation in Puget Sound, that threshold matters more than any single return-period map.
    [They] also propose Expected Annual Flooded Area (EAFA) as a probability-weighted alternative to the binary "inside or outside the 100-year zone" label…”

  3. It was really foggy out on the ocean today!
    Almost no winds until we reached mouth of the bay. I was happy to take Mom out for her very first sailing experience ☺️ She found it to be very relaxing. We saw some seals, mergansers, few American coots & a couple of buffleheads.
    Back at RVYC on August 22.

  4. I had a great first solo #sailing session this afternoon. Winds were tricky today. Winds changed directions 5 times in 2 hours. Lots of adjustments on my sails today.

    I got yacht club approval to take my Mom out as my passenger, for her very first sailing adventure, tomorrow morning! I'm pretty stoked about that. Mom has never been in any sailboat before! I'm not taking her very far because she gets scared of open ocean (while I love open ocean!). It will be very nice to take my Mom out for her first sailing experience 😊⛵️

  5. Saving some time by getting towed out to sailing practice course markers, by one of the #RVYC safety/coach #ZodiacBoats.

    I'll upload brief clip of sailing back to marina after practicing some demo race course navigation, soon. Had some nice winds during my first solo adaptive #sailing session today ⛵️😊

  6. Ocean water is rushing miles underneath the ‘#DoomsdayGlacier’ with potentially dire impacts on #SeaLevelRise

    By Laura Paddison, CNN
    Published May 22, 2024

    "The #ThwaitesGlacier in #WestAntarctica — nicknamed the 'Doomsday Glacier' because its collapse could cause catastrophic sea level rise — is the world’s widest glacier and roughly the size of Florida. It’s also #Antarctica’s most vulnerable and unstable glacier, in large part because the land on which it sits slopes downward, allowing ocean waters to eat away at its ice.

    "#Thwaites, which already contributes 4% to global #Sea Level rise, holds enough ice to raise sea levels by more than 2 feet. But because it also acts as a natural dam to the surrounding ice in West Antarctica, scientists have estimated its complete collapse could ultimately lead to around 10 feet of sea level rise — a catastrophe for the world’s #coastal communities."
