Dataset Information

Spatial datasets to define operational boundaries within four marine basins delineated by distance from shore, depth, EEZ and protected status, accompanied by maps and statistical summary tables.

ABSTRACT: This data article provides several datasets delineating, illustrating and summarizing marine regions within exclusive economic zones (EEZs) of 69 coastal states within the Atlantic, Baltic/North Sea, Mediterranean and Caribbean marine basins. Datasets include two GIS feature classes stored in a Version 10.0 file geodatabase: (1) A polygon feature class delineating operational boundaries within EEZs based on sovereign authority, distance bands from shore, depth ranges, and whether the region lies within a recognized protected area, and (2) A polyline feature class of shorelines for each coastal state. Both feature classes are fully described in the metadata. Datasets also include Excel files summarizing each marine basin and coastal state, summarized by area and proportion of all combinations of distance, depth and protected status. Datasets also include maps illustrating and describing all combinations of distance, depth and protection status, plus shoreline length, for each coastal state and for each marine basin. Datasets also include Visual Basic for Applications (VBA) code files used to generate all datasets, summary tables and maps. These datasets support analysis described in "Assessment of the geographical potential for co-use of marine space, based on operational boundaries for Blue Growth sectors" (van den Burg et al., 2018), and allow readers to extend the regional assessments described in that article down to individual country-level assessments.

Project description:We investigate the extent to which functional structure and spatial variability of intertidal communities coincide with major biogeographical boundaries, areas where extensive compositional changes in the biota are observed over a limited geographic extension. We then investigate whether spatial variation in the biomass of functional groups, over geographic (10's km) and local (10's m) scales, could be associated to species diversity within and among these groups. Functional community structure expressed as abundance (density, cover and biomass) and composition of major functional groups was quantified through field surveys at 20 rocky intertidal shores spanning six degrees of latitude along the southwest Atlantic coast of Argentina and extending across the boundaries between the Argentinean and Magellanic Provinces. Patterns of abundance of individual functional groups were not uniformly matched with biogeographical regions. Only ephemeral algae showed an abrupt geographical discontinuity coincident with changes in biogeographic boundaries, and this was limited to the mid intertidal zone. We identified 3-4 main 'groups' of sites in terms of the total and relative abundance of the major functional groups, but these did not coincide with biogeographical boundaries, nor did they follow latitudinal arrangement. Thus, processes that determine the functional structure of these intertidal communities are insensitive to biogeographical boundaries. Over both geographical and local spatial scales, and for most functional groups and tidal levels, increases in species richness within the functional group was significantly associated to increased total biomass and reduced spatial variability of the group. These results suggest that species belonging to the same functional group are sufficiently uncorrelated over space (i.e. metres and site-to-site ) to stabilize patterns of biomass variability and, in this manner, provide a buffer, or "insurance", against spatial variability in environmental conditions.
