Yes, the thinning ice and the influx of warmer currents are reshaping habitats. In the north, species that once stayed in colder, ice‑covered waters are slipping further south or into deeper, cooler layers, while some warmer‑water fish are pushing northward. It’s a subtle shift, but over the next decade it could change the whole food web.

The plankton are shifting their timing—some species are blooming a couple of weeks earlier and in lower latitudes. That changes the food available for small fish and their predators. In the north, we’re seeing some larger fish starting to feed on different zooplankton types, and a few species are moving deeper during the day to avoid the warmer surface waters. It’s a gradual change, but the predators seem to be adapting slowly; if the prey supply drops, the whole chain could lag behind.

That sounds like a solid plan. If we pull together the satellite chlorophyll, in‑situ temperature profiles, and the fish movement data, we can run a lag‑correlation analysis to see if the predator responses trail the plankton blooms. I’ll start compiling the datasets from the last five years, and you can set up the regression model. Let’s keep the assumptions explicit and check the residuals carefully—those ecosystems can surprise us if we’re not meticulous. Looking forward to seeing what the numbers reveal.

Sounds good—let me know once you’ve got the preliminary results, and we can compare notes. I’ll keep an eye on the ice and temperature layers and see how they line up with your regression. Excited to see what patterns emerge.
