  1. The Multi-disciplinary Ocean Sensors for Environmental Analyses and Networks (MOSEAN) Program Tommy Dickey (UCSB) Al Hanson (SubChem Systems) Dave Karl (University of Hawaii) Casey Moore (WET Labs) Grace Chang (UCSB) Derek Manov (UCSB) Frank Spada (UCSB) ASLO/TOS 2004 Ocean Research Conference Honolulu, Hawaii

  2. Goals of MOSEAN1. Development & testing of new interdisciplinary instruments for moorings and other autonomous sampling platforms2. Science – ecology, biogeochemistry, climate, HABs, pollution. Special interest in episodic and extreme events.MOSEAN Testbed Mooring Sites1. Santa Barbara Channel – a coastal settingCHAnnel Re-locatable Mooring (CHARM)2. Hawaii HOT site – an open ocean settingHALE-ALOHA Mooring

  3. 35o00’N N Legend SB CHARM 50 Point Conception Santa Barbara 34o30’N 100 Santa Barbara Channel 300 La Conchita 500 50 Ventura 300 300 100 500 100 50 100 Pacific Ocean Santa Cruz Island 34o00’N San Miguel Island Santa Rosa Island Anacapa Island 120o30’W 120o00’W 119o30’W CHARM Mooring Site in Santa Barbara Channel #1 May 19 – Oct. 2, 2003 #2 Feb. 11 – May 5, 2004 s Bioluminescnce PO4 ADCP Real-time data telemetry to La Conchita Automatic data processing and web display

  4. ac-s hyperspectral absorption-attenuation instrument Deployed Feb. 11, 2004 off La Conchita, CA Data are being telemetered in real-time (Free-wave modem) WET Labs

  5. MOSEAN Instrument Package Conductivity and Temperature Sensors, Fluorometer, and Hyperspectral Radiance, Irradiance, and Bioluminescence Sensors

  6. 3-Channel Spectral Fluorometer (Left) & Single-Channel Fluorometer (Right) WET Labs Copper Shutter After Before

  7. Single channel nutrient analyzer for long-term deployments Nitrate, phosphate, silicate, ammonia, iron SubChem/WET Labs

  8. Lingulodinium polyedra Lingulodinium polyedra Pseudonitzschia australis Photo provided by Rosalba Dominguez Red Tide Pseudonitzschia bloom “Normal” • Pseudonitzschia australis domoic acid event  sea lion and dolphin mortality (May – June 2003) • Lingulodinium polyedra  anoxic conditions  massive fish kill (August – October 2003) • See poster by Chang et al., Hyperspectral Signatures in Case 2 Waters session
