[pacificdata.org](pacificdata.org) – the Pacific Data Hub – is the central repository of open data and knowledge products about the Pacific region. Anyone can access the public data on the Pacific Data Hub. You are encouraged to search, reuse and share the data on pacificdata.org.

The Pacific Data Hub holds a large and diverse collection of data, data insights, publications, and knowledge products on the Pacific across key sectors, including population statistics, fisheries, geoscience, agriculture, aquaculture, energy, education, human rights, climate change, and oceans, and it continues to grow.

While the intention is for the Pacific Data Hub to become a multi-stakeholder-owned and managed platform, it is currently a product of the Pacific Community (SPC), and as such is governed by SPC’s internal documents.

Let us know how you are using the data hub or if you wish to contribute to our data catalogue.

Projection of tuna biomass (skipjack, albacore, yellowfin and bigeye tuna) in response to climate change simulated by the Spatial Ecosystem and Population Dynamics Model (SEAPODYM, http://www.seapodym.eu/ and https://github.com/PacificCommunity/seapodym-codebase).

Here, we provide the unfished biomass dynamics (i.e. without considering any fishing). Therefore, the observed trends are only due to the projected climate change. The projection is performed over the period 2011−2100 under IPCC's RCP 8.5 scenario to simulate "business-as-usual" climate anomalies. We provide the mean of the ensemble, composed of 4 simulations performed with different Earth System models (IPSL-CM5A, MIROC, GFDL-ESM2G and MPI-MR). For each of the four tuna species we provide both the total biomass (adults + juveniles) and the larvae abundance.
