I put some rockweeds in the aquarium to test the resilience to heat waves 🌱🥵🌱
But this post is about the amount of filamentous algae accumulating in the aquarium with continuous supply with water from the Oslofjord, that is suffering from serious eutrophication.

This is bad 😖🌱

Let me talk about dulse (Palmaria palmata) og a #PhycologyFriday This red algae grows along the coast in many countries. It’s easiest collected in the intertidal zone.
Dulse can be used in many ways – often dried, and as a slightly nutty flavour. Dulse contains protein, fat, and vitamin A.

My great colleague Hartvig dressed up with Desmarestia aculeata (called «kjerringhår» in Norwegian, which means «old woman’s hair» or «hag’s hair». He is 75 years old and is still going strong - working with blue and having fun all along our >100 000 km long coast 🌱🥰💪🏼

Women collecting rockweeds in southern Norway in 1912.

Norwegians have a long transition for using rockweeds for food, animal feed, fertilisers. Some of our species have names like Sheepweed (Pelevetia canaliculata) and Pigweed (Ascophyllum nodosum)

Walking in the city of Trondheim (mid Norway) during a workshop on tools for mapping and value assessing marine habitats.
I had to press this to get a green light to cross the road. I am now waiting for the effect…..

I looks like a drone image, doesn’t it? Of a rockweed intertidal with a scientist doing frame analyses. At least, that was what I saw 😂 At the Autumn Exhibition. But it is a hand-knotted wool rug if a person cleaning a plastic bag. But that IS a rockweed intertidal, of that I am certain 💙

No drones, no AI, not very high-tech at all, only hard working people shaking and rinsing Ascophyllum to get all associated fauna out for biodiversity analyses 💪🏼🌱 #PhycologyFriday

Days and days on the field, collecting rockweeds along gradients and across zones; hours and hours in the lab, shaking, sieving and bottling - and this is what we end up with. It looks like such a tiny result, but it is SO much work behind it 😅

The perfect place - a deserted boat house - to store our Ascophyllum samples, with associated species, in the Olderfjord in Arctic Norway. In my home sown, and redesigned, rockweed mesh bags 💪🏼

Greetings from Arctic Norway, 70.7°N. Tomorrow we go to one of our Ascophyllum sites to measure Asco properties, identify all species in frames and associated with the rockweed. Or aim is to compare structure, function and biodiversity in harvested areas with the unharvested control.

This is one long Ascophyllum nodosum - about 260 cm long 📏and almost 20 years old 💪🏼🌱 Found at a beach on the Midwest coast (Tautra in the Trondheim fjord) of Norway while getting ready for this year’s seagrass monitoring #PhycologyFriday

Doing what I am not - absolutely not - good at 😫, which is redesigning mesh bags and getting them ready for Ascophyllum nodosum rockweed “hunting” in Arctic Norway (to capture the rockweeds and all associated species). Spent hours - hours - just getting my head around the borrowed sowing machine 😅

Struggling with the Chorda filum that we unwillingly detach and that makes our underwater camera quite heavy under the seagrass monitoring #PhycologyFriday
In some meadows we have high density of Zostera marina, but moderately dense coverage of C. filum in a «spaghetti canopy» above the seagrass
