Algae MAp App Now Available! A GEO Google Earth Engine Project

Congratulations to the Algae MAp team for their newly published application and article describing the use of Google Earth Engine for monitoring water quality on a continental scale!  The AlgaeMAp application is a partnership of the Federal University of Pelotas (UFPel), INPE,  the Federal University of Rio de Janeiro (UFRJ) and Michigan State University.  The project is one of two water quality projects awarded  in July 2020 by joint selection of the Group on Earth Observations (GEO) and Google Earth Engine.

The article was entitled AlgaeMAp: Algae Bloom Monitoring Application for Inland Waters in Latin America and was just published in Remote Sensing.

The AlgaeMap Application was developed within the Google Earth Engine (GEE) platform and provides historical and current images containing information on the trophic status, chlorophyll-a concentration and algae bloom in reservoirs and lakes in Brazil. The images used are from the MSI/Sentinel-2 satellite, which since 2015 provides images with 10m of spatial resolution. In the application, the NDCI (Normalized Difference Cholorophyll Index) image collection used has a spatial resolution of 30 m.

You can access the Algae Alert App and the usage tutorial on the UFPEL Geotechnology Laboratory website.

This is an open project and the team wants to extend it to other areas/regions and are seeking partnerships and collaborations.  If interested , please contact:


ARSET Training – Monitoring Coastal and Estuarine Water Quality: MODIS to VIIRS

Check out the upcoming NASA ARSET training (Available in Spanish too!)

September 14, 16, & 21, 2021: 11:00-12:30 EDT (UTC-4)

REGISTER 12:00 – 1:30 PM EDT (UTC-4)

Estuaries are water bodies where freshwater from rivers and streams meets with seawater. Coastal and estuarine waters are important to humans as they are highly productive habitats supporting a variety of fish and wildlife. These environments also provide resources, economic benefits, and ecosystem services. That being said, the water quality of these coastal and estuarine areas is of great importance. This is heavily influenced by the flow of nutrients and sediment from land-based sources. The flow of nitrogen and phosphorus in particular enhances algal bloom and hypoxia in the water, highly affecting benthic creatures like fish, shellfish, and crustaceans. Water quality in estuaries also depends on several factors such as their size, location, coastal land use, quality of freshwater runoff, and tidal effects from the sea.

Remote sensing observations from Aqua/MODIS have enabled us to monitor coastal and estuarine water quality since mid-2000. As MODIS nears the end of its mission, it is important to transition to VIIRS (first launched in 2011) to provide continuity with the MODIS instrument and add to the moderate-resolution, long-term data record of water quality monitoring in estuaries. This intermediate-level webinar will provide an overview of recent satellites and sensors used for extending the MODIS long-term water quality time series, specifically focusing on VIIRS image processing using the NASA Ocean Color software, SeaDAS. This webinar will point out similarities and differences between MODIS and VIIRS and demonstrate water quality monitoring procedures using these sensors in selected coastal and estuarine regions.

NEON Program – Job Opening – Field Operations Manager – Puerto Rico

The National Ecological Observatory Network (NEON) Program is currently seeking a Field Operations Manager. This position is located in Guanica, Puerto Rico.


Occasional travel outside the region will be required.

NEON is a continental-scale ecological observation facility sponsored by the National Science Foundation that gathers and synthesizes data on the impacts of climate change, land use change and invasive species on natural resources and biodiversity. The observatory is designed to collect high-quality, standardized data from field sites across the continental United States, Alaska, Hawaii and Puerto Rico.


This position manages a broad scope of scientific inquiry, managing a multi-disciplinary team of field scientists who collect measurements related to botany, invertebrates, soils, micrometeorology, eddy flux, aquatic biology and water quality at four NEON sites in Domain 04 – Puerto Rico (Atlantic Neotropical).


  • Plan, schedule, conduct and ensure accurate execution, within NEON scientific parameters and annual budget, of all maintenance, repair and field sampling activities for 4 NEON field sites.
    • Coordination for instrument maintenance is required for sensors, data acquisition system, power distribution system and supporting infrastructure (i.e. tower, instrument hut, boardwalks).
    • Coordination for field observations and collection are conducted using approximately 30 different protocols and multiple SOP’s with varying schedule requirements based on local ecosystem and current field conditions.
  • Recruit, train and manage all regular and temporary personnel supporting field office, lab and field site tasks.
  • Encourage and actively support diversity, equity, and inclusion within the team, organization and/or field
  • Act as liaison between regional stakeholders, including educational and research organizations, local property owners and the general public and Battelle.
  • Communicate NEON status and activities, local activities and partnerships, and regional issues and concerns to appropriate regional stakeholders and Battelle staff. Work with regional stakeholders to resolve issues or concerns.
