Today is #seaweedsaturday for our indoor and greenhouse plants. One thing #GardenersWorld has taught us is the importance of weekly feeding, even during the winter. I need to emphasize that more in the GrowZone app, so will add that to the planned upgrade. apps.apple.com/us/app/growz...
Elk kelp! #Pelagophycus #SeaweedSaturday #MarineLife 🦑🌊
Im a day late for #phycologyfriday but #seaweedsaturday can be a thing right?

So much energy and fun at #SeaweedSaturday in Portland, ME. Good eats, art and demos. Thanks to all those who made this happen for the second year in a row. Copies of #TheWakameGatherers went home with many new friends : )
Thank you @leeandlow.bsky.social

Seaweed Saturday is 4/26 at Gulf of Maine Institute, Portland & I'll be there w/ The Wakame Gatherers. Seaweed Saturday features arts, seaweed panels, marketplace, tastings, hands-on activities, food trucks & more!

A greeny-brown seaweed with some large bladders, shaped like small bird eggs (various sizes). Air bladders help the wracks reach light to photosynthesize; broken pieces of A nodosum also disperse by means of these flotation devices. This seaweed is edible and has health benefits, but also absorbs heavy metals; only fresh growth should be consumed.
#SeaweedSaturday
Ascophyllum nodosum (Egg or knotted wrack), another of Scotland's 5 native wracks. Note the singly-spaced air bladders (one per year) along thick, un-ribbed fronds. Supports barnacles, periwinkles and isopods, providing food for birds. Common and edible.
Serrated wrack is usually brown, the edges are jagged like a carpenter's saw and down the middle of the fronds is a deep grooved midrib. In the pic the piece is hand-sized, but the species can reach up to 1m.
#SeaweedSaturday
Fucus serratus (Serrated Wrack aka Toothed or Saw Wrack) is one of 5 native Scottish wracks. Note the saw-like edges, deep midrib and absence of air bladders on flat fronds. Supports over 100 marine species; fresh tips can be eaten in salads/stews. Common/widespread
A small, gregariously bladed #kelp, Laminaria sinclairii, for #seaweedsaturday. I love the golden reflections in the second image. Photo from San Francisco.
I’m holding a spring “scale” attached to a green clump of the seaweed *Acrosiphonia coalita*. The slider inside the PVC tube is displaced a distance proportional to the force required to pull the seaweed from the rock.
I’m holding the seaweed, still attached to the spring scale, now pulled off the rock.
We are measuring a bunch of traits of seaweeds to help us understand their roles in marine systems. To measure attachment strength, I’ve lassoed the base of this green #seaweed w/ a cord attached to a calibrated spring, then pulled it off the rock to measure the force required. #SeaweedSaturday
Seapalms (Postelsia palmaeformis) the #oregon coast for #seaweedsaturday. Throwback to a few years ago.
