  1. Marine Mammal Density Data Gap Assessments and Update for the Phase III AFTT Study Area Density Data Gap Filling Workshop objectives Marine Geospatial Ecology Lab Duke University November 14 – 16, 2012

  2. Workshop Objectives This workshop will explore the current state of the Navy Marine Species Density Database (NMSDD), the Navy Acoustic Effects Model (NAEMO), current animal density modeling efforts, and outline next steps for future marine animal density modeling.

  3. General Objectives The purpose of this effort is to develop & implement methods to fill data gaps from the CetMap products to cover the remaining areas in the AFTT study area. The primary focus of this task will be to develop and implement a quantitative approach to extrapolate the data from the CetMap working group, both spatially and temporally for all marine mammal species present within the AFTT area. These marine density data will be the most up-to-date definitive data for acoustic effect analysis in the upcoming Phase III AFTT EIS.

  4. Workshop Objectives • Build consensus on next generation modeling approaches or ensembles for the USN Atlantic Testing and Training Range (AFTT). • Discuss making project outputs publically available and re-usable through the web and web services. • 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.

  5. Workshop Objectives Additional objectives… • Set the stage for potential parallel efforts to be conducted for Pacific training areas… • Begin the process of adding sea turtle density assessments more fully into the process…

  6. Atlantic Fleet Testing & Training – AFTT study area

  7. Density of protected species ship & aircraft surveys Atlantic Fleet Testing & Training Area Filling Density Data Gaps ? Atlantic & Gulf of Mexico ? ? ? ? ? The offshore–distant data-gap problem….

  8. Density of protected species ship & aircraft surveys Filling Density Data Gaps ? The port & pier-side data-gap problem….

  9. Workshop process Moderated discussions • Question driven; • Solutions focused; • Product oriented; The outcomes of this workshop are intended to directly inform future priorities and activities

  10. Workshop Objectives (1) Build consensus on next generation modeling approaches or ensembles for the USN Atlantic Testing and Training Range (AFTT). • General Discussion Topics: • Appropriate types of modeling approaches; • Error & uncertainty; • Model validation & testing; • Merging different models and information;

  11. Workshop Objectives (2) Discuss data gap assessment, gap filling methods, and creating a hierarchy of data quality. • General Discussion Topics: • Gaps in space & time; • Available data types and priorities; • Role of expert knowledge; • Hierarchy of data quality.

  12. Workshop Objectives (3) Discuss the future beyond this modeling effort including data standards and model processes that enable repeatability of existing models. • General Discussion Topics: • Data standards and classification of data types; • Best practice standards for models; • Ensemble models;

  13. Workshop Objectives (4) Discuss making project outputs publically available and re-usable through the web and web services. • General Discussion Topics: • Data and model delivery: clients & users; • Product types; • Discovery metadata services; • Data & model development, delivery & archival process.
