My new paper in PLOS ONE, modeling how humans are impacting marine spp & ecosystems through climate change & activities incl fishing, shipping, nutrient pollution (doi.org/10.1371/journa…). It even got some press (newsweek.com/marine-species…)! #OpenScience @nceas @OceanHealthIndx

Ten years of the Ocean Health Index! I am so happy to work with such an amazing team of scientists. Check out the new website: oceanhealthindex.org/news/2021-scor…

Invisible lines marked on maps are hindering current efforts to conserve the world’s marine species such as sea turtles, according to #UQresearch. @UQscience @leslieamlwch @CarissaJoyKlein @cyclonewatson Read more: tinyurl.com/yjzvbqgp

Love Thy Neighbour (or at least Collaborate With Thy Neighbour) key for ocean conservation More than 90% of mapped marine species live in or travel across multiple political jurisdictions. New article @GlobalChangeBio doi.org/10.1111/gcb.15… @UQ_CBCS @UniMelb @NCEAS @TheWCS

What does it take to restore an #ocean to good health & how can @OceanHealthIndx help? Susa Niiranem from @sthlmresilience's #podcast @Rethink_Earth chats with OHI's creator @BSHalpern & Thorsten Blenckner, creator of OHI spinoff @BalticHealthInd! 🔗 rethink.earth/what-does-a-he…

Ck our new @Nature pub! Achieving global targets for biodiversity conservation needs every tool. #OECMs provide the opportunity to recognize & support different forms of governance, including areas managed by Indigenous and local communities. nature.com/articles/d4158…

Our paper in @ScienceMagazine now has a cool interactive Shiny app, thanks @ian_brunjes! ohi-science.nceas.ucsb.edu/visualizing_hu… (the paper ain’t bad either: At-risk marine biodiversity faces extensive, expanding, & intensifying human impacts science.sciencemag.org/content/372/65…) #shiny @nceas @brenucsb

@DocFroehlich @ScienceMagazine thanks Halley! Note that the oharascience version of the app is out of date - the *real* one is here: ohi-science.nceas.ucsb.edu/visualizing_hu… (free shinyapps.io account only gets like 25 hours of user time a month, but the @NCEAS version should have better bandwidth)

Our new paper in @Science: At-risk marine spp face human impacts across 57% of their ranges, those impacts are expanding & intensifying. @UNBiodiversity #Post2020 framework #30by30 can help! Analysis & figs 100% #rstats @rstudio. @nceas @brenucsb science.sciencemag.org/content/372/65…

Our new paper in @Science identifies areas of high/low & increasing human impact on 1271 at-risk marine species, to inform protection targets & goals for @UNBiodiversity #Post2020 framework #30by30 science.sciencemag.org/content/372/65…

@oceanhealthindx for #BritishColumbia studied health of BC marine ecosystems 2001-2016 across 8 themes; overall score improved from 75/100 to 83/100 @PLOSONE @nceas journals.plos.org/plosone/articl… All code on GitHub #openscience github.com/OHI-Science/oh…

15 years of @oceahealthindx scores for #BritishColumbia tailored to include local values incl. salmon, First Nations Resource Access. @PLOSONE @nceas journals.plos.org/plosone/articl… All @oceanhealthindx code is on GitHub #openscience github.com/OHI-Science/oh…

Cool new paper asks the question “If we were managing oceans in 2050 and looking back, what research, primary or synthetic, would wish we had invested in today?” frontiersin.org/articles/10.33… @nceas @snapp also was inspiring to see that #interdisciplinary working group in action!

@villasenor_jc @github Likewise - I look forward to working on more papers with you @villasenor_jc !

Oh, and if you get a chance to work with @oharascience, don't think it twice. Best collaborative coding experience I've had! And yes, this was all done in #rstats, and the code is on @github: github.com/oharac/spp_ris…

As @oharascience so eloquently says, "To conserve marine biodiversity, we must first understand the spatial distribution andstatus of at-risk biodiversity." Well, we've done just that (and by "we", I mean Casey). Read the paper here -> onlinelibrary.wiley.com/doi/full/10.11…

We mapped global dist. of extinction risk of marine biodiversity - for 83% of the ocean, >25% of assessed marine spp are threatened: onlinelibrary.wiley.com/doi/epdf/10.11…

Fishing removes old fish from the sea, and that could spell trouble for fish populations. hakaimagazine.com/article-short/… Me for @hakaimagazine

@jafflerbach @MikeRSpencer @juliesquid same - #rstats for analysis, QGIS for viewing or manual fiddling

New interactive #shiny app for our new @PLOSONE paper! Explore 5 yrs of changes in ocean health ohi-science.nceas.ucsb.edu/plos_change_in… @ohiscience #rstats

5 years of @OceanHealthIndx communicating the health of our oceans - what's changed over that short span, & why? journals.plos.org/plosone/articl…

We could easily replace "marine biologist" with climate scientist or really nearly anything at this point! h/t @markrstoll cc @JaneLubchenco
