Download Mid-Atlantic Wildlife Studies: Distribution and Abundance of Wildlife along the Eastern Seaboard 2012-2014. This 32-page summary publication explores aspects of the mid-Atlantic ecosystem; describes our survey and analytical approaches; and presents a range of results, featuring several case studies on specific species or phenomena.
The Executive Summary for the technical report is also available here.
We analyzed weather surveillance radar (NEXRAD) to identify potential offshore migration pathways and timing, as well as environmental and temporal variables correlated with these patterns. Weather radars send microwaves into the atmosphere to detect precipitation. These microwaves also indicate the locations of flying animals, such as birds, bats, and insects. During migration, “blooms” of migratory activity can be seen surrounding radar units on unfiltered radar maps (in the header image, irregular green and yellow areas represent precipitation, while the more circular blue and gray areas are migratory activity). Innovations developed during this study allowed for targeted exclusion of meterological phenomena, greatly improving the sample size of available data and allowing for examination of migratory activity even during nights with precipitation, which had previously been impossible.
