3 years ago meeting notes:
-
work space: Southern Maine CC- Brian? -- UMaine Damariscotta?
-
collaborators: -- Brian Tarbox (SMCC): bucket design, worked in Portland Harbor- contact -- Damian Brady (UMaine, based in Damariscotta): drifter- temp, salinity -- Curtis Bohlen (Casco Bay Estuary Partnership, EPA): defining problem (water movement) https://www.cascobayestuary.org/about-us/staff/ ----- has been wanting mathematical model/ground truth -- Jim Manning (worked w Brian): big drifter guy, entire GOM -- Ernie Tru (retired?): Casco bay currents model, background on water movement of Maine coast, May 2012 model ---- movement of water in Back Cove of Portland Harbor, Portland treatment plant spill --> sewage goes into Back Bay
-
pre made drifters? -- look at Brian, Damian's designs, try to make it more reproducible? -- depends on science question
-
getting data into public sphere?
-
instrumentation -- local GPS
-
http://www.neracoos.org/drifters -- archived drifter tracks: Jim Manning- emolt (temp, lobster traps) http://www.emolt.org/ -- host data?
-
drift patterns of lobster traps and ghost gear, plastic bottles: origin? -- release drifter at lobster trap sites? (bottom currents, tidal currents) -- buoys and lines follow surface currents -- high energy environments, sheltered areas -- Allen Island (Muscongus Bay): things wash up on curved cobble beaches- scuba survey? -- Casco Bay: Peak's Island Ferry --> ghost gear, rent kayak? -- local shellfish warden: more interest inland: tidal rivers, estuaries (more gap in data); help in deploying, tracking, recovery -- aquaculturists as another resource:
-
not enough time to set up physics model, but should be able to compare survey tracks to Ernie's model
-
FV com: Ernie uses higher resolution than NOAA (funded) https://github.com/BigelowLab/fvcom -- not fine enough resolution for figuring out: where does spat go? where does treatment water go? -- no online archive: have to capture as it goes by -- only offshore? no coast? except maybe Scituate Harbor which is separate model -- Ben takes rasters of surface values, saves at Bigelow
-
ground truthing Ernie's model: nitrogen concentration? -- Mike: looking at nitrogen gradient moving down Portland Harbor? -- volume needed for nitrogen sampling: 40-60 ml -- time range: few hours, can freeze for months --> deployment within a day -- syringe? -- niskin bottle inspiration: elastic band triggers little bottle to close -- trigger mechanism: clock? raspberry pi? -- rosette? -- temp, salinity, niskin collector
-
nicole poulton: Home Depot made niskin bottle: make smaller
-
boothbay public library has 3D printer,
-
nutrient criteria group: meeting coming up (Curtis, treatment plat operators, state scientists)
https://casconorwich.org/pages/YarmouthWWTP.html
-
ernie model , look backwards to find data?
-
lodging -- no space in Residence -- Darling? Center, with Damian -- McKee house? Bigelow -- community renting in Boothbay?
USM, SMCC summer housing?
with: Turner, Nick, Ben, Mike
motivation: nitrogen pollution + currents in Portland Harbor, downstream of water treatment plant(s) -- current research teams?
drifter logistics -- type of instrumentation- instantaneous nitrogen levels, or automated sampling? -- inspiration: open CTD, bucket drifter? OpenCTD_ConstructionOperation (1).pdf Bucket+Drifter+Methodology+Brief-2.pdf -- deadline on design? -- access to workbench? 3D printer?
Github lab notebook -- github usernames to tag in future meetings?
Haverford funding confirmation: -- start and end dates -- address where I'll be staying -- Nick: stipend form Research Stipend Authorization Form 2021.pdf
