overview of mdl course: introduction to marine data management ii murray brown...
TRANSCRIPT
Course Summary
• Assembly, synthesis & display of many ocean and atmosphere data products
• Synoptic, climatological• Measured, modeled• In situ, remotely sensed
• Software platforms: ODV, IDV, SAGA• Classwork (Liberia) and personal projects (AOI)• Final project presentations
Basic Approach
• Read articles in OTA digital library (19)• Course: 40 sequential exercises (Liberia)• Individual student projects (TBD)• Area selection• Problem-solving & detective work
• Personal datasets as desired – ask the guru• Student presentations
Student Preparation
• Lesson 1 – Reading list (pre-course)• Lesson 2 – Instructor’s opening talks, including
the Integration Diagram• Lesson 3 – Computer setup
4. Area of Interest
Geographic Information Systems methods to map ocean areas, from basic to complex
4, continued
High resolution ancillary data for coastal zone considerations
5. Initial Collection from the World Ocean Database
Repatriation of data from the World Ocean Dataset
5, continuedBuilding managed data collections in Ocean Data View: OSD, PFL, CTD, XBT/MBT
6. Basic Data Analyses
Standard graphical analyses for marine research and publications
7. Exporting ODV Products
Ocean Data View exports data subsets or interpolations for use in other systems, especially GIS
8. Data Contouring
Your first (?) brush with contouring
9. Grid and Raster Analysis with SagaGridding scattered data for further analyses
9, continuedPractice in making “standard products” for academic and professional work, and for new technologies
9, continued
Methods for Level 3 remote sensing products – synoptic and climatological
10. Global Relief Data Products
Working with relief grids permits estimates of unpublished contours and rough assessment of flooding risk
Shelf depth contour estimates
11. Vector ChartsWinds (below) and surface current vectors from climatologies
12. Managing Operational Data
Nowcasts and forecasts of ocean scalar parameters
12, continued
Building global salinity grids with L2 swaths
12, continued
Near-real-time monitoring of ocean chlorophyll … possibly the “holy grail” of remote sensing
Postscript
• The MDM II course is possibly the most difficult short-course in oceanography, due to the large number of datasets, the short duration, and the complexity of the software. BUT, the student exercises have been uniformly excellent over the years.
• You are strongly recommended to keep your PPT file, update or improve it whenever you can, and use it for demonstrations of your skills.
