4 Underway Reconnaissance Breakout FULL SPEED: Hull mounted: Hull mounted: 1- ADCP – 38 kHz (200k$ ??) 2- ADCP – 150 kHz (75k$ ??) 1- XBT: 800m (<10k$) 2- Wave Recorder -– same motion package as met mast – fixed laser altimeter (Riegl) - (15 – 20k$)

5 Underway Reconnaissance Breakout FULL SPEED: Towed: Towed: 2- Magnetometer cost??? 1.5- Moving Vessel Profiler – deck space and cost issue cost ($500k) – - perhaps underway CTD Ocean Science Oceanside CA (cost???) - perhaps underway CTD Ocean Science Oceanside CA (cost???) 1- Continuous Plankton Recorder – issue of archive and analysis – SAHFOS – Sir Allistar Hardy 2- Passive Acoustic?? Stationary – Navy surplus??? 3- GEK – Geoelectric Kinetograph (surface current) 50k$ 3- Towed Blimp for remote sensing (20k$) 3- UAV??

6 Underway Reconnaissance Breakout FULL SPEED: New Developments: (would be nice priority) New Developments: (would be nice priority) Full speed bio sampling?? Are there ways to design a net or sampling strategy to allow sampling while underway at full speed? Towed pump that can sample water at deeper depths while underway (below seasonal thermocline – 50 – 100m) Hull mounted laser profiler for chlorophyll fluoresence Approaches to automated bird and marine mammal observations Reliable full-speed towed undulating vehicle

7 Underway Reconnaissance Breakout ONCE PER DAY: CTD Rosette - several hours for full depth or partial (top 1000m?) Camera Frame w/ CTD and photos and sampler? Freefall camera w/ CTD? Yes, it's worth it, but what is important ? Water column folks will tell us.

8 Underway Reconnaissance Breakout AUV as underway tool – Broken Stick Surveys?? Questioned efficiency at this point in time but as AUV capabilities evolve – may become much more viable option NOAA has a EAGLE RAY AUV – 2000 m capable w/ EM2000 MBES
