Comparing marine species ranges for OHI global assessments

We are excited to have a paper published in PLOS ONE today: “Aligning marine species range data to better serve science and conservation”. In it we examine global maps of nearly 25,000 marine species ranges that are available publicly from the International Union for the Conservation of Nature (IUCN) and AquaMaps. You can read the paper here, or check out our interactive web application where you can explore our results and compare range maps of more than 250 different species.

The importance of open data science tools in science: a list of references

Open data science is the combination of open science, data science, and team science. We promote and practice this with the Ocean Health Index by using software tools that make our work transparent, reproducible, and shared publicly online. These concepts are being discussed more and more in the news and in the academic literature. There are so many great articles on these topics that we have started this list, along with a quote from the article to give a sense of its content.

Five years of global Ocean Health Index scores

Today the Ocean Health Index (OHI) announces the completion of the fifth annual global Ocean Health Index (OHI) assessment at the 17th annual Global Environment Facility Large Marine Ecosystem meeting in Paris. Global OHI scores represent ocean health for 220 coastal nations and territories and are calculated with the same methods and best available information each year. The OHI, established in 2012, is a partnership led by scientists from the National Center for Ecological Synthesis and Analysis (NCEAS) at the University of California at Santa Barbara and Conservation International.
