“Studies on historical and future distribution of marine species are frequently limited by the lack of relevant data on abiotic components (IPCC, 2014), especially when working over large areas (Robinson et al., 2017). Important advances have been achieved in the last years regarding availability of global information on physical and chemical driven forces affecting species distributions. WorldClim (Hijmans et al., 2005) marked a milestone in terrestrial species distribution studies, as it opened the opportunity to address global research studies with high resolution. Other databases including historical and projected variables in the terrestrial environment, mainly temperature and precipitation, such as Climond (Kriticos et al., 2012), Climate wizard (Girvetz et al., 2009) or Chelsea (Karger et al., 2016) have emerged recently. However, in the marine environment the number of global databases is limited. Bio-Oracle is the most valuable reference because it provides surface and benthic layers for water temperature, salinity, nutrients, chlorophyll, sea ice, current velocity, phytoplankton, primary productivity, iron and light at high resolution and global coverage (Assis et al., 2017; Tyberghein et al., 2012). Other remarkable databases are MARSPEC (Sbrocco and Barber, 2013), offering variables derived from bathymetry, slope, salinity and sea surface temperature, Aquamaps (Ready et al., 2010), focused on marine animals, or Hexacoral (Fautin and Buddemeier, 2002), with the aim to understand spatial and temporal patterns in biogeochemistry and biogeography. Some databases cover both land and sea areas, such as the MERRAclim (Vega et al., 2017), which offers decadal data of 19 derived variables of air temperature and humidity atmospheric water vapour….
Trying to comply with these requirements and using the best data available, to our best knowledge, this study presents the open access database on climate change effects on littoral and oceanic ecosystems (OCLE), an ecological-driven database of present and future hazards for marine life in Europe….”
