Reach out to Great Lakes scientists please

Some good advice in here but one critical piece I always give is this:

Get a hobby. Preferably a mildly social one. One that has NOTHING TO DO WITH SCIENCE. NOTHING.

You need friends. Not colleagues. FRIENDS. Friends who will love you no matter your research prospects...

The Swedish University of Agricultural Sciences launches large-scale fish tracking – aiming to provide new insights about fish in the Baltic Sea SLU has deployed 80 acoustic receivers along two lines in the Baltic Sea. By listening for signals from tagged fish, the receivers will reveal migration routes and uncover new insights on life beneath...

FINALLY! 🥳

A Baltic Sea Tracking Network is on the way!! Thanks in part to a receiver loan from @oceantracking.bsky.social members of ETN based at SLU & LUKE (Finland) have deployed what we hope is just the beginning 💪

This package has data that can be used instead of nycflights13 to teach joins, and also to look at temporal trends and draw maps. It has to coolest hexsticker vahdatjavad.github.io/ecotourism/ and cute creatures: mantarays, gouldian finches, glow worms and orchids

I haven't used {DeclareDesign} before, but I have been using {marginaleffects} in my simulation-based power analyses for the past year or so, and I recommend you do too.

Opinion: Let’s both celebrate – and worry about – our Great Lakes on World Lake Day Canada’s freshwater benefits us greatly - and we need to return the favour

Obviously, and laughably wrong. Whales do not in fact fly into windmill blades. Entanglement in fishing gear, and getting hit by ships is the main cause of right whale deaths. And the other whale species are doing just fine in the Atlantic.

African Union backs campaign to replace Mercator map that distorts Africa's size Organizers behind the Correct The Map campaign say the Mercator map's shrinking of Africa minimizes the continent's global influence — and is just plain inaccurate.

We’ve been able to successfully tag alewife with v7 and v6 Innovasea tags in Lake Ontario and Huron. We have also have also early detections indicating they survived and have been moving around.

Thank you for clarification, given the four points you bring up I can see its usefulness, especially using with native pipes and type sensitivity.

I get that it’s type safe but overall replace_when() seems redundant to me.

Are these not just a wrapper around case_when()?

This is the way

Researchers ID organisms behind algae blooms near Barker's Island By sequencing DNA from a bloom near Barker’s Island in Superior last fall, researchers linked the toxins to Microcystis aeruginosa. The Minnesota Sea Grant called it a “breakthrough discovery.”

We had an amazing time on Sunday at Earth Day at Malden Park. Thanks to everyone who stopped by our booth to chat and learn about water monitoring, and the work we are doing with RAEON. We are looking forward to seeing you again at our community science events starting this month! shorturl.at/FJN6L

Quarto articles, in the `vignettes/articles/*` sense, don't seem to work · Issue #2821 · r-lib/pkgdown I'm working on making usethis::use_vignette() and usethis::use_article() work for .qmd. In that PR (r-lib/usethis#2085), I feel like I've got the right files going in the right places, etc., and .q...

That’s fair…I didn’t know that pkgdown could render qmd, figured it was restricted to rmd…you learn something every day. Not sure if you’ve seen this GH issue on pkgdown. It’s resolved but maybe this has popped back up.

Is there a specific reason for using quarto here versus rmarkdown?

Same here I just learned st_nearest_point() and st_within(). I used the combination of the 2 to snap points that fell outside a polygon. It’s such a great tool!

Thanks - let me know if any issues arise.

I second pathroutr

The to and from column idea comes from network analyses, specifically this blog post.

www.jessesadler.com/post/network...

You could then create to and froms in your detection data similar to this blog post. And then left join the to and from line strings to the detections based on a pasted column of the to and froms

Going to chime in here I’m not sure about directly curved lines but check this blog post to see how to use pathroutr to make shortest paths between points
