The recent Intergovernmental Panel on Climate Change (IPCC) Special Report on Oceans and the Cryosphere in a Changing Climate suggests sea level rise may be best understood as a slow onset disaster for Pacific Island countries and, in particular, low lying atoll nations. Sea-level rise, coastal flooding and surge inundation is an increasingly pressing problem across the urban Pacific.
There exist no future projections of fishery conflict that consider wider societal trends. This paper builds four future fishery conflict scenarios by using a multimethod approach. The scenarios take place between 2030 and 2060 in the North-East Atlantic, the East China Sea, the coast of West Africa, and the Arctic and explore implications of ongoing trends in conflict-prone regions of the world. They function as accessible communication tools and aim to foster anticipatory governance capacity in the pursuit of future ocean security.
The IUCN (the International Union for Conservation of Nature) World Conservation Congress called for the full protection of 30% of each marine habitat globally and at least 30% of all the ocean. Thus, we quantitatively prioritized the top 30% areas for Marine Protected Areas (MPAs) globally using global scale measures of biodiversity from the species to ecosystem level.
Despite global policy commitments to preserve Earth's marine biodiversity, many species are in a state of decline. Using data on 22,885 marine species, we identify 8.5 million km2 of priority areas that complement existing areas of conservation and biodiversity importance. New conservation priorities are found in over half (56%) of all coastal nations, including key priority regions in the northwest Pacific Ocean and Atlantic Ocean.
This study reports plastic debris pollution in the deep-sea based on the information from a recently developed database. The Global Oceanographic Data Center (GODAC) of the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) launched the Deep-sea Debris Database for public use in March 2017. The database archives photographs and videos of debris that have been collected since 1983 by deep-sea submersibles and remotely operated vehicles. From the 5010 dives in the database, 3425 man-made debris items were counted.
To establish an estimation procedure for reliable catch amount of illegal, unreported and unregulated (IUU) fishing, light-gathering fishing operations in the northwestern Pacific were analyzed based on the Visible Infrared Imaging Radiometer Suite (VIIRS) day/night band (DNB) data provided by the Suomi National Polar Partnership (SNPP) satellite. The estimated fishing activities were compared with the navigation tracks of vessels obtained from the automatic identification system (AIS).
