The NES-LTER produces observational data, derived data products, and model data. Observational data are obtained in real-time from moored underwater instruments, underway and from sampling on research cruises, and post-cruise with laboratory analyses. These data and data products are categorized in support of the 5 core research themes. Our physical samples include water samples, filters, plankton net samples, and fish specimens.

What are we measuring right now?

Current Sea


Martha’s Vineyard Coastal Observatory (MVCO)

Environmental parameters are measured in real-time from South Beach, Martha’s Vineyard, MA, and/or one mile offshore.

Imaging FlowCytobot (IFCB)

Images of phytoplankton are provided every ~20 minutes from the underwater microscope at MVCO.

Northeast Coastal Ocean Forecast System (NECOFS)

An interactive map that displays present physical oceanographic conditions and the forecast for the next 3 days.

What have we measured?


What we have measured recently

Underway and CTD data from our day cruises to MVCO with WHOI’s R/V Tioga, as well as ship-provided data from our Transect cruises on R/V Armstrong, are available online at WHOI’s Data Library.

We provide a web-based REST API for a subset of data from our Transect cruises, including underway and CTD data, nutrients, and chlorophyll.


Data available through DataONE

The NES-LTER provides data through DataONE including underway data from University-National Oceanographic Laboratory System (UNOLS) cruises that are in the Rolling Deck to Repository (R2R) and curated data products that are hosted by the Environmental Data Initiative (EDI) repository. We will provide access to genetic sequencing data through the National Center for Biotechnology Information (NCBI).

Code repositories available in GitHub

Our software repositories are publicly available on GitHub. Presently we distinguish our nes-lter-ims Python library from notebooks (Jupyter, R) to access and perform analysis of cleaned data.

Our affiliated programs, each of which has data available online:

The Northeastern Regional Association of Coastal Ocean Observing Systems (NERACOOS) aggregates data from many providers in the region. Some data from MVCO are available through NERACOOS. NERACOOS is developing a model viewer for the Northeast Coastal Ocean Forecast System (NECOFS).

NOAA also provides physical oceanography products for Woods Hole.
