Depth-Temperature envelope for two basking sharks tracked for 365 days

🧵 3/4 Continuous time series revealed a wider thermal envelope than previously assumed. #BaskingSharks seem to tolerate Arctic waters below 1°C for hours and endure temperatures below 5°C for several weeks.

Daily depth time series across habitats occupied by the sharks across the year. Dots highlight bioluminescence events.

🧵2/4 Diving patterns were highly context-dependent. Following topography, light, temperature, and bioluminescent biomass, #sharks seemed to be tracking their planktonic prey year-round across habitats.

#BaskingSharks of the #ArticCircle 📢Tracking the second largest #fish for a full year, our new paper invites you on a deep #dive into the life of a cold water giant between the Barents Sea and the Azores 🐟❄️🌊🏝️🇳🇴

📢 New IMR research reveals alarming effects of overfishing on herring 🐟 Age-selective fisheries caused an 800-km poleward shift in spawning, disrupting collective memory and migration patterns. #FishMigration #FisheriesManagement
