Inner Shelf DRI Monthly Meeting 2017-08-02
attendees: Just about everyone
Agenda
- Ship Ops brief
- Daily communications/teleconference
- Readiness Review
Ship Ops Brief
- Strawman plan posted on the blog
- Moorings will dictate final timing/availability for the surveys
- Turnaround cruise will have more opportunity for added surveys
- May add 17th or 18th of Sept survey day for Oceanus
- Could receive most recent satellite imagery via Roland/Hans for internal wave tracking
- NLIW lines represent 1 hour out and back
- Distance is approx. e-folding of dissipation scale
- Oceanus and SR will have radar recording
- 3 modes of surveys, focused, Refraction, broad scale
- 12 to 14 transects per cycle
- CTD surveys
- Stratification obs for modeling out to 200-250 m for N transect
- Cross-shelf at Pt. Sal
- Headland Eddies
- Eddie timescale – hour
- Vorticity decay also observable with planes (SAR, IR) and drifters. Question about wind regime for SAR (offshore winds shadowed by headlands)
- Meso/submeso -scale flow
- Sample on box perim. (blue takes 6 hrs @ 4 kts)
- Repeated to determine lengthscales and statistics
- One day for vorticity alongshore transects
- Combine vorticity and mesoscale surveys
Daily Briefings
- Skype of call – will try calling first, cell coverage expected to be okay
- 2000 local time every day (can use APL conference line)
- Planes will txt points of contact for each group on takeoff, use airband radios while in the air
Drifters
- SWIFT has AIS, bright float, and light for avoidance
- SIO drifters are low profile (mostly submerged), have lights
- NPS drifters are orange
Readiness review
- APL plane – green, SAR is yellow due to permissions in review
- APL in situ – green
- SIO plane – greenish, airspace looks green
- SIO Drones – operate Oceano beach
- SIO ship – green
- NPS ship – green, permits in for Pt Purisma moorings and NSFW moorings and active acoustics
- Hans/Roland – greenish on satellite, yellow/green radar on Oceanus
- Spindrift – green on wave buoys, constructing mooring
- Tony – green on radars, yellow onLF6 power, green on met buoys
- SIO drifters/moorings – green
- OSU – radars green
- OSU ship – green on ship ops and moorings
- Sproul – yellow/green
