Spatially explicit conservation efforts to identify, designate, and prioritize protected areas or biologically signifi-
cant areas require analyses beyond basic species distribution and abundance studies, including assessments of
migration patterns, habitat use, and ecological drivers of behavior. With the advent of alternate survey methods
and platforms within the marine environment (e.g. satellite telemetry, passive acoustics, photo identification,
nesting site monitoring and genetic sampling) in addition to traditional shipboard or aerial visual surveys, re-
searchers have been developing novel analytical and modeling methodologies to fulfill such in-depth ecological
assessments. This trend has raised interests and needs not only in filling spatial, temporal and ‘ecological’ gaps
but also in the synthesis of these disparate data from multiple methods/platforms. OBIS–SEAMAP, a thematic
node of the Ocean Biogeographic Information System (OBIS) specializing on marine megavertebrates, takes a
unique approach to data integration into the OBIS–SEAMAP database to enable novel applications of a global
biogeographic database. In this paper, we summarize our efforts to accomplish this integration and to develop
novel mapping and visualization tools available on the OBIS–SEAMAP web site. We also discuss advantages
and implications of an integrated database in advancing ecological assessments and modeling efforts based on
preliminary assessments of the OBIS–SEAMAP data and derived products. Finally, we make critical suggestions
for the design and function of biogeographic databases to make contributed data more useful for conservation
efforts.

1. Introduction
Spatial conservation efforts require ecological understanding
beyond the distribution or abundance of the target species for more
effective conservation strategies and management. This need is particu-
larly clear for the designation of marine protected areas or the delineation
and prioritization of biological hotspots. For example, the Convention on
Biological Diversity (CBD) has defined seven criteria for the identification
of Ecologically or Biologically Significant Areas (EBSAs) in the open ocean
and deep seas: 1) Uniqueness or rarity; 2) Special importance for life his-
tory of species; 3) Importance for threatened, endangered or declining
species and/or habitats; 4) Vulnerability, fragility, sensitivity, slow recov-
ery; 5) Biological productivity; 6) Biological diversity; and 7) Naturalness
(CBD, 2009). Identification of EBSAs that meet these criteria relies
on spatio-temporal assessments of migration patterns, habitat uses
(breeding and foraging), site fidelity, behavioral differences by sex or
age class, and other ecological aspects (CBD, 2009; Olsen et al., 2009;
Redfern et al., 2006). Such global scale ecological assessments require ex-
tensive collections of high-quality biological data, which was the driving
purpose for establishing global biogeographic databases such as the
Ocean Biogeographic Information System (OBIS; http://www.iobis.org;
Ausubel et al., 2010; Costello and Vanden Berghe, 2006; Grassle, 2000).
In the case of marine megavertebrates (e.g. marine mammals, seabirds
and sea turtles), most data in such databases come from museum speci-
mens or sightings recorded during visual surveys (both line-transect
and opportunistic surveys by ship or plane). Visual sightings provide con-
firmation of species' presence in surveyed locations and are often used to
examine marine biodiversity across taxa, geographic distribution and
abundance of species (Mora et al., 2008; Tittensor et al., 2010; Webb
et al., 2010). Given the costs and restricted spatial and temporal coverage
of visual surveys (Ackleh et al., 2012; Marques et al., 2009), however,
these platforms are limited in filling spatio-temporal gaps for marine
megavertebrates, many of which are long-distance migratory or elusive,
deep-diving species (Gedamke et al., 2001; Olsen et al., 2009). Moreover,
visual surveys are not optimal platforms to collect animal characteristics
