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!
