My new paper in PLOS ONE, modeling how humans are impacting marine spp & ecosystems through climate change & activities incl fishing, shipping, nutrient pollution (https://t.co/OeoCAutMUr). It even got some press (https://t.co/t0oxhVIGAX)! #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: https://t.co/L4ySuODisX

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.

What does it take to restore an #ocean to good health & how can @OceanHealthIndx help?

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. https://t.co/H6PWEo29OK

Our paper in @ScienceMagazine now has a cool interactive Shiny app, thanks @ian_brunjes! https://t.co/rDlnSsZA6M (the paper ain’t bad either: At-risk marine biodiversity faces extensive, expanding, & intensifying human impacts https://t.co/HZBuhSwIq6) #shiny @nceas @brenucsb

[Casey O'Hara @oharascience]

@DocFroehlich @ScienceMagazine thanks Halley! Note that the oharascience version of the app is out of date - the *real* one is here: https://t.co/rDlnSsZA6M (free https://t.co/ooMSRyrByx account only gets like 25 hours of user time a month, but the @NCEAS version should have better bandwidth)

[Casey O'Hara @oharascience]

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 https://t.co/AGynTcPq0E

[Casey O'Hara @oharascience]

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 https://t.co/AGynTcPq0E

@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 https://t.co/MPo9pvajJU All code on GitHub #openscience https://t.co/ZQ3BgiUcQQ

[Casey O'Hara @oharascience]

15 years of @oceahealthindx scores for #BritishColumbia tailored to include local values incl. salmon, First Nations Resource Access. @PLOSONE @nceas https://t.co/MPo9pvajJU All @oceanhealthindx code is on GitHub #openscience https://t.co/ZQ3BgiUcQQ

[Casey O'Hara @oharascience]

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?” https://t.co/jeXhAykED4 @nceas @snapp also was inspiring to see that #interdisciplinary working group in action!

[Casey O'Hara @oharascience]

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

[Casey O'Hara @oharascience]

We mapped global dist. of extinction risk of marine biodiversity - for 83% of the ocean, >25% of assessed marine spp are threatened: https://t.co/IHZOquNrjt

Fishing removes old fish from the sea, and that could spell trouble for fish populations. https://t.co/CR7oBNvhz5 Me for @hakaimagazine

New interactive #shiny app for our new @PLOSONE paper! Explore 5 yrs of changes in ocean health https://t.co/3aXp6MH5Df @ohiscience #rstats

[Casey O'Hara @oharascience]

5 years of @OceanHealthIndx communicating the health of our oceans - what's changed over that short span, & why? https://t.co/PpxknMG1h1

We could easily replace "marine biologist" with climate scientist or really nearly anything at this point!
