An overview on clay boulders at the bottom of the lake.

Faint view of the sailboat wreck lying at 5-7 mtr depth. Seen from the surface.

Dutch waters are known for its bad visibility. Well in comparison with tropical waters thats true. 1-4 mtr is common. Yesterday I measured a #Secchi depth of 13,8 mtr. I could even see the wreck at 5-7 depth from the surface. There are still #Microcystis colonies present at 5°C. #cyanobacteria

Went #snorkeling today collecting #plankton. Floating around getting friggin cold as my old drysuit is becoming a semi-drysuit. Saw a big bloated #perch lying on the bottom. and little green plants. I love this stuff. #freshwater #Secchi depth 10 mtr.

Annalisa #Terranova è addirittura più arrogante e ignorante di Mario #Secchi e Italo #Bocchino 🤬🤬🤬

ma siamo davvero sicuri che invitare certa gente sia sinonimo di pluralità?

Stunning grayscale image of Comet McNaught's ion tail captured by the SECCHI instrument aboard the STEREO satellite. The comet's tail, extending at least seven degrees, is dramatically swept back by the solar wind, showcasing filamentary rays. The bright coma is oversaturated in the image. This is a remarkable view of the brightest comet in recent decades.

Sechi sugli attacchi di Giorgia Meloni: "Saviano ha un ruolo politico". Gruber: "Ma che razza di discorso è" | LA7 Sechi sugli attacchi di Giorgia Meloni alla festa di Atreju battibecca con Lilli Gruber

queste affermazioni sul ruolo politico di Saviano da parte di Secchi, per “giustificare” le ingiustificabili affermazioni della Presidente del Consiglio sono gravissime 🤬
