"Det er vores vurdering at konklusionen må blive, at der ikke kan gives tilladelse til vandindvinding, på baggrund af projektelementerne herunder opstemningen, uddybning mm. Dette bevirker at lovligheden af værket bortfaldet den dag afslaget give" viborg-folkeblad.dk/samfund/saa-...

Så er det slået fast: Tangeværket kan ikke fungere på lovlig vis
Viborg Kommune bad om en ekstern vurdering af omstridt rapport om Tangeværkets drift og Tange Søs helbred. Konklusionen er klar.

"Der er ikke penge til at måle efter pesticider i grundvandet i år" Det lyder som en dårlig joke 😱 #dkgreen www.altinget.dk/miljoe/artik...

Ministerium sætter målinger af pesticider på pause: "Så vidt jeg ved, er det første gang i grundvandsovervågningens historie" - Altinget
Manglende målingerne betyder, at vi ikke har ordentligt overblik over mængden af pesticider i grundvandet, lyder det fra en ekspert på GEUS. DN kalder situationen for ”meget ubegribelig”. (Opdateret m...

We’re deploying 106 receivers in the inner Oslofjord for the NMBU cod project with @oceantracking.bsky.social. This study tracks migration and movement shifts in two cod ecotypes and assessing habitat changes. Using Thelma and Innovation equipment, an open protocol is key to the project!

Modtog i 2022 Ebbe Kløvedal Reichs Demokratistafet. Det er en interessant pris for ud over æren, får man den opgave at gøre noget for demokratiet. Jeg skrev bl.a. en lille bog. Den er nu tilgængelig online for den gavmilde pris af 0 kr. online.fliphtml5.com/gwgkt/dzpl/#...

Out in the LilleÅ river, to search for spawning grounds for trout, after their spawning season. The number of spawning grounds can help estimate the status of the population #salmotrutta #trout #seatrout @kimaarestrup.bsky.social

Just a nice little spawning ground you think. But in fact the first Sea trout to spawn here in 500+ years. And only because barrier at Mill pond further downstream was removed. #riverrestoration

Yesterday after work walking along local stream looking for this. Can you guess what it is? Hint, it’s not created by humans.

Counting departing smolts and returning adults in index rivers is essential to estimate marine survival and track population trends of Atlantic salmon (Salmo salar). However, mortalities between coun....

After some delays caused by gas build-up in the chambers, we're finally off to the races! Always satisfying to see all the parts come together :) =[🐟]= =[🐟]= =[🐟]= =[🐟]=
A top view of an aquatic respirometry system composed of two baths containing four chambers each. The four chambers on the left are smaller than the ones on the right. These chambers are used to measure oxygen consumption in fish. There are a lot of wires and cables going around, in good crazy-scientist experiment fashion :)

Today we downloaded and serviced the acoustic receivers in the last (and smallest) of the three Danish Straits, completing the 2024 downloads. If you have acoustic tagged fish in the Baltic or North Sea and think they could have been detected, check the ETN database. @fishybiologistkim.bsky.social

Cold fieldwork in Danish chalk stream River Villestrup, trying to recapture adult Sea trout tagged with heart rate loggers. Gin clear water and thousands of Sea trout since dams and weirs were removed a decade ago. @mariepedaccini.bsky.social with a male and female. @fishybiologistkim.bsky.social

Yesterday we downloaded and serviced the acoustic Thelma receiver array in The Sound (Øresund) between Denmark and Sweden. Data will be uploaded into the European tracking network database.

Tagging sharks today with acoustic transmitters. Today’s species is Spiny Dogfish. Excited to follow their migration over the next three years with European Tracking Network. @aquatictracking.bsky.social @fishybiologistkim.bsky.social #NorTrack #DtoTrack

The Turnu Măgurele-Nikopol hydropower project on the Lower Danube has been added to the EU's priority investment list, despite the fact it will increase flood risk, threaten protected areas and the survival of critically endangered species, and violate the EU's own policies. Read more:

Last week's news❗❗ It is maintenance time, we downloaded the 26 #ThelmaBiotel receivers composing our high-precision array located in Cíes Island🏝️ This array is set to detect #OpenProtocol (OP) acoustic transmitters🔎 I cannot wait to see what the fishes have been up to👀🦈 #TrackingNotSlacking

⚠️⚠️ Innovasea has moved to encrypt their coding schemes to ensure that their tags can only be detected by their receivers. Imagine if Apple decided that iPhone users could only call other iPhone users? You could no longer call your friend who owns an Android. Important thread 👇
