Geographic Scope of the NOAA Fisheries Pacific Islands Region

• Need for basin-scale or

global datasets

• Need high-resolution data

in coastal areas

Data offerings can be overwhelming

NOAA OceanWatch – Central PacificData Discovery

Based on identified users and user needs, OceanWatch serves a curated list of datasets.

• long-term global datasets for fisheries and ecosystem research

• near-real-time SST for daily monitoring of fishing conditions and bycatch mitigation.

• For each parameter: longest possible time-series of consistent observations or climate data records (CDR) to enable users to examine temporal trends.

• When available, gap-filled or reanalyzed level 4 data.

NOAA OceanWatch – Central PacificData Discovery

• SST

• Ocean color : chlor-a, Kd490, PAR

• Altimetry: SLA, geostrophic currents

• Wind

• Salinity

• L3 or L4

What is easy and useful? - ERDDAP

• ERDDAP is a data server that gives users a simple, consistent way to download subsets of

scientific datasets in common file formats and make graphs and maps.

• ERDDAP unifies the different types of data servers so users have a consistent way to get

the subset of data they want, in the format they want.

• Users can use ERDDAP’s web page to request data or use ERDDAP's RESTful web

services directly from any computer program (Matlab, R, e.g.).

• It’s possible to create several catalogs of ERDDAP datasets from a single ERDDAP server

to customize offerings for different audiences

PROSCONS

• Extra work

• Can’t just relink

datasets from

other ERDDAPs

• Takes more disk

space

• Data tailored to

users

• Faster access

since files are

stored locally

Training/Capacity building

•3-day (free!) course aimed at NOAA participants who want to learn how to access & use satellite

data

•The course was developed by Cara Wilson and the late Dave Foley, both at NMFS/SWFSC/ERD,

in conjunction with Ted Strub at the Cooperative Institute for Oceanographic Satellite Studies

(CIOSS) at Oregon State University in Corvallis, OR.

•The course was initiated by funding from NOAA’s R&O project at CoastWatch’s West Coast Node

in 2006. The course was conducted with no funding support 2007-2012, some funding has been

obtained for the courses since 2013.

•Since 2018, the course goes viral through the East Coast CoastWatch Node and the Pacific

OceanWatch Node!

• Lectures

• Remote sensing basics

• Applications of satellite data

• SST

• ocean color

• wind, salinity, altimetry

• Tools

• Tutorials on Voyager, ERDDAP, ArcGIS, NetCDF/Panoply

• R scripts

Soon: Python, Matlab

Barriers

• Product comparison :

Which primary productivity product to choose?

• Long-term sensor-less ocean color : OC-CCI not updated routinely –

about 6-month delay
