BRIDGE-BS ERDDAP

The goal of this web page is to give you easier access to Black Sea Scientific data products, which are being developed in frameworks of the BRIDGE Black Sea project. The BRIDGE-BS project produces and maintains a number of data products, among which are:

• The BRIDGE-BS database serving the data of Black Sea in-situ observations, particularly, historical data from past R/V surveys and projects; the data generated by national/regional monitoring programmes; the data from BRIDGE-BS R/V surveys, and the time-series data for Pilot Sites,
• Satellite products,
• Outputs of and biogeochemical models for Black Sea,
• Results of statistical analysis.

While the BRIDGE-BS Database is the autonomous data product with its own web interface, the other gridded and tabular data products are served by this ERDDAP server.

The satellite products consist of daily satellite level L3 datasets for Chl-a, KD490 and SST for the period 2000 to 2020. They are subsets of the global NASA/GSFC/OBPG products extracted from the (Ocean Color web portal). The products cover the whole Black Sea area and have a spatial resolution of 4 km. They intended to serve as input for model validation and support the long-term time series analyses. While the access to satellite datasets is provided by this ERDDAP server, also the visualization of Chl-a satellite data is available with the dedicated WEB-GIS application.

The model result datasets include:

• Test outputs from Black Sea biogeochemical model,
• Test outputs from Black Sea hydrodynamic model,
• Test outputs from IPSL climate model for Black Sea.

The access to the data is provided through the ERDDAP data server that gives you a simple, consistent way to download subsets of gridded and tabular scientific datasets in common file formats and make graphs and maps.

    Search for Interesting Datasets

• Do a Full Text Search for Datasets

  Search

• View a List of All 13 Datasets

• Search for Datasets by Category

  Datasets can be categorized in different ways by the values of various metadata attributes. Click on an attribute (cdm_data_type, institution, ioos_category, keywords, long_name, standard_name, variableName) to see a list of categories (values) for that attribute. Then, you can click on a category to see a list of relevant datasets.

• Search for Datasets with Advanced Search 

• Search for Datasets by Protocol

  Protocols are the standards which specify how to request data. Different protocols are appropriate for different types of data and for different client applications.
   

  Protocol	Description
  griddap datasets	Griddap lets you use the OPeNDAP hyperslab protocol to request data subsets, graphs, and maps from gridded datasets (for example, satellite data and climate model data). griddap documentation
  tabledap datasets	Tabledap lets you use the OPeNDAP constraint/selection protocol to request data subsets, graphs, and maps from tabular datasets (for example, buoy data). tabledap documentation
  "files" datasets	ERDDAP's "files" system lets you browse a virtual file system and download source data files. WARNING! The dataset's metadata and variable names in these source files may be different than elsewhere in ERDDAP! You might prefer using the dataset's Data Access Form instead. "files" documentation
  WMS datasets	The Web Map Service (WMS) lets you request an image with data plotted on a map. WMS documentation

   

• Developers of computer programs and JavaScripted web pages can search for datasets via

  • ERDDAP's RESTful search services
  • ERDDAP's allDatasets tabular dataset that has a row of information for each dataset
  • ERDDAP's OpenSearch 1.1 Service

• Search Multiple ERDDAPs

  There are two unofficial ways to search multiple ERDDAPs for datasets: Search Multiple ERDDAPs and ERDDAP Dataset Discovery.

Converters
In addition to serving data, ERDDAP has some handy converters:

Metadata
ERDDAP has an
FGDC Web Accessible Folder (WAF) with FGDC‑STD‑001‑1998 metadata files and an
ISO 19115 Web Accessible Folder (WAF) with ISO 19115‑2/19139 metadata files for all of the geospatial datasets in this ERDDAP.

RESTful Web Services
You can bypass ERDDAP's web pages and use ERDDAP's RESTful web services (for example, for searching for datasets, for downloading data, for making maps) directly from any computer program (for example, Matlab, R, or a program that you write) and even from web pages (via HTML image tags or JavaScript).
