Ups & Downs for Oceanography
I.Summary This series is directed at Establishing importance of oceanographic data in everyday life Exploring instrumentation/platforms available, focusing on gliders Discussing examples of data collected Practicing applying such data
II. Objectives After this series, you will be Able to provide a suite of examples of oceanographic data that impact ‘day-to- day’ life Able to discuss the various tools available to collect such data Able to navigate various web sites to obtain and use such data
III. Materials Computer lab with internet access Handouts: 1.URL maps 2. “Ideas” sheet
IV. Procedure A.Lecture on the topic B.Consult ‘URL’ map to navigate various relevant sites C.Consult ‘ideas’ sheet or come up with own ideas to complete project
Projects (choose 1) “Wow! Fishing at xxx is going to be great today” “Why is the beach water cold today?” “We just lost $xxxx because the captain did not check at prevailing currents”
The Plan
I. Predicting the Ocean
A. Important B. Data needed Beach erosion Shipping
Fishing
Biological phenomena
II.Quest for data
A. Dynamic environment
B. Real time or near-real time data Why? Collection Storage Analysis
2. Data collection Use assets –Land based –At sea –Satellites
3. Storage Retrieval facilitated
4. Data analysis
Data scrutiny – accuracy
Data scrutiny – consistency
Data scrutiny – artifacts
III.Parameters A. CTD B. Backscatter C. DO D. Wave data E. Current vector F. Other
IV.Collection methods A. Mission requirements B. Endurance
V.Some of the assets A.Satellites B.Cabled seafloor observatory C.Land based radar D.Vehicles 1.Ships 2.Submersibles
A. Satellites
Chlorophyll
Sea surface temperature anomalies – latitude/temperature anomalies
True color imagery
B. Cabled seafloor observatory

C. Land based radar

D. Vehicles
1. Ships
2. Submersibles
a.Manned b.Un-manned i.ROV ii.AUV
Non-autonomous assets have shortcomings comparable to ships
ii. An AUV – Glider ‘Unpowered’ vehicle High endurance Adequate payload capacity Programmable Communicates
VII. What is a glider? Magic!?
Forward motion without power! Takes instructions and reports back
VI.Survey of coastal ocean to 200 m
VIII. Types of data Real time Discrete/’cleaned’ Archived
Uses Real time –Tracking a current event –Can be unwieldy Discrete –Loss of time/event line –Economical
Archived –Analyzing changes in parameters –Usually distilled
