Marine Geospatial Ecology Lab

Agenda: US Navy Marine Mammal and Sea Turtle Modeling workshop

Workshop Objectives

The Navy Marine Species Density Database (NMSDD) is among the primary resources for the Navy’s compliance with a suite of federal environmental regulations that apply to the marine environment. This workshop will explore the current state of the NMSDD, the Navy Acoustic Effects Model (NAEMO), current animal density modeling efforts, and outline next steps for future marine animal density modeling.

  • Build consensus on next generation modeling approaches or ensembles to prototype for the USN Atlantic Testing and Training Range (AFTT).
  • Discuss data gap assessment, gap filling methods, and creating a hierarchy of data quality
  • Discuss the future beyond this modeling effort including data standards and model processes that enable repeatability of existing models.
  • Discuss making project outputs publically available and re-usable through the web and web services.
