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?

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

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

The NES-LTER provides data through several community repositories, including DataONE member nodes:

We also provide data through NASA's SeaWiFS Bio-optical Archive and Storage System (SeaBASS).
We 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) and examples to access and perform analysis of cleaned data.
