“…It has demonstrably improved conservation outcomes for endangered whales in this region by optimizing research activities, facilitating dynamic risk-mitigation measures, and engaging with the ocean industry and the public. WhaleMap has also already been cited in several scientific publications (Baumgartner et al, 2020;Gervaise et al, 2021;Johnson et al, 2020;Koubrak et al, 2021;Kowarski et al, 2020). We are not aware of any equivalent software in existence.…”

“…In 2016, the IWC created a strategic plan to monitor collisions between cetaceans and vessels in order to develop approaches and solutions to achieve a permanent reduction in ship strikes by 2020. Although effective in terms of mortality reduction, the restriction of maritime routes and fishing zones as well as the reduction of authorised speed can create conflicts of interest with fishing and maritime transport 63 . However, the main threat to the recovery of whale populations in the coming years may likely be climate change 17,18 , including the increased spread of disease 19 and the decrease in krill prey density and southward contraction of geographic distributions 35 .…”

Limiting climate warming below 2°C requires both reducing anthropic greenhouse gas emissions and sequestering more atmospheric carbon. Natural Climate Solutions (NCS) rely on the ability of ecosystems to capture and store carbon. Despite the important role of marine megafauna on the ocean carbon cycle, its potential as a NCS has not yet been explored. Here, we quantify the amount of carbon potentially sequestered by five baleen whale species across the Southern Hemisphere between 1890 and 2100 through both the sinking of carcasses after natural death and the fertilisation of phytoplankton by nutrients in faeces. At their pre-exploitation abundances, the five whales could sequester 10.6 106 tonnes of carbon per year (tC.yr-1) but this natural carbon sink was reduced at 2 106 tC.yr-1 in 1965 due to commercial whaling. However, the restoration of whale populations could sequester 8.7 106 tC.yr-1 at the end of the 21st century suggesting an efficient but neglected NCS that remains to be estimated globally including all marine vertebrates.

“…Globally, entanglements in shing gear pose signi cant risk to endangered and threatened whale populations [4][5][6][7] . Environmental impacts from climate variability and change have exacerbated whale entanglements in recent years in particular sheries [8][9][10][11][12] . These entanglements often involve species that are legally protected under the Endangered Species Act or Marine Mammal Protection Act and thus result in temporary shery closures.…”

Whale entanglements with fishing gear, exacerbated by changing environmental conditions, pose significant risk to whale populations. Management tools used to reduce entanglement risk, for example temporary area restrictions on fishing, can have negative economic consequences for fishing communities. Balancing whale protection with sustaining productive fisheries is therefore a challenge experienced worldwide. In the California Current Ecosystem, ecosystem indicators have been used to understand the environmental dynamics that lead to increased whale entanglement risk in a lucrative crab fishery. However, an assessment of socio-economic risk for this fishery, as in many other regions, is missing. We estimate retrospectively the losses from ex-vessel revenue experienced by commercial Dungeness crab fishers in California during two seasons subject to whale entanglement mitigation measures. In the 2020 fishing season, our results suggest total revenues would have been $14.4 million higher in the Central Management Area of California in the absence of closures and other disturbances. In the 2019 fishing season, our results suggest ex-vessel revenues would have been $9.4 million higher in the Central Management Area and $0.3 million higher in the Northern Management Area. Our evaluation should motivate the development of strategies which maximize whale protection whilst promoting productive, sustainable and economically-viable fisheries.
