1 Oceanic Monitoring and Sampling Phoebe Woodworth-Jefcoats Ecosystems and Oceanography Program Ecosystem Sciences Division PIFSC 5 April 2016

2 Background Draw on a set of tools Compliments ongoing work Supports West Hawaii IEA U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 2

3 Science and Management Objectives Monitoring ecologically important features: TZCF Determining islands’ oceanography: American Samoa, Marianas Support of the West Hawaii IEA Validating satellite and model data Gaining insight on subsurface processes U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 3

4 Collaborators NMFS Office of Science and Technology NOAA Teacher At Sea program University of Hawaii at Manoa and Hilo Hawaii Pacific University Northern Mariana College University of Guam Guam National Park Service CNMI Division of Fish and Wildlife Micronesian Environmental Services American Samoa Department of Marine and Wildlife Resources American Museum of Natural History U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 4

5 Data and Tools NOAA Ships CTDs (temperature, salinity, oxygen, fluorometry, HPLC, flow cytometry) Active acoustics (scattering layers) Passive acoustics (cetaceans) DIDSON (collaboration, micronekton components) Trawls (micronekton components, collaborations) Trapping Video observing systems Fishing Tagging or Animal-borne Instrumentation Turtles Tuna Swordfish Cetaceans Whale sharks Gliders Collaboration with PSD and UH-SOEST (temperature, salinity, fluorometry, ambient sound) Satellite remotely-sensed Covered in OceanWatch talk U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 5

6 Results – Subtropical Frontal Zone Nearly 20 years of data Early validation of satellite data, tied surface data to subsurface processes Climate work has shown region to be particularly vulnerable to change, beginning to see some results indicated by climate work Climate change or climate variability? U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 6 Howell et al. 2015

7 Results – Island Oceanography Islands’ influence on oceanography and ecosystem productivity American Samoa CNMI U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 7 Suntsov and Domokos 2013

8 Results – West Hawaii IEA Active acoustic data used in cetacean habitat mapping U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 8 Abecassis et al. 2015

9 Results – Autonomous Seaglider 3 deployments in partnership with PSD and UH-SOEST Surveyed eddies, West Hawaii grid U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 9

11 Successes and Challenges Successes Satellite validation Monitoring to determine causes of change Challenges Need seamlessness between consecutive chief scientists: maintaining time series, retaining knowledge U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 11

12 Future Directions Streamlining and standardizing data collection and storage – in partnership with ITS Novel/custom sampling techniques U.S. Department of Commerce | National Oceanic and Atmospheric Administration | NOAA Fisheries | Page 12
