Metocean and Wildlife Surveys, Reporting, and Visualization
Metocean and Biological Buoys

To help offshore wind developers achieve maximum productivity with minimal environmental impact, Ocean Tech Services LLC (Ocean Tech) and Normandeau Associates Inc. (Normandeau) have teamed up to offer buoy-based metocean and wildlife surveys to facilitate successful permitting of offshore wind farms in the U.S. and overseas. more...

Buoys are custom-designed for simultaneous metocean and biological monitoring. Using calibrated sensors and proven remote communications, we deliver the highest quality data, analysis, results, and system reliability to our clients so they can make informed decisions regarding project design, construction, operations, and maintenance activities.

Our approach is to work with you to develop a cost-effective, clearly defined study design and sampling strategy based on the unique needs of your project.

Platforms of Opportunity


Floating LiDAR and traditional weather buoys are used by Ocean TechĖNormandeau to host atmospheric, oceanographic, and biological sensor systems. Each buoy is custom-fitted with the sensor packages required by customers for a specific project area. A full suite of environmental and biological data collection is offered through additional sensor packages deployed on the buoy or sea bed. We collect data day and night, above and below the oceanís surface.

In addition to metocean systems, optional sensors include:

VHF antennas and receivers (MOTUS/Lotek/CTT) to provide species-specific information from tagged birds and bats. In collaboration with FWS, this technology provides data on tagged endangered species including Red Knot, Piping Plover, and Roseate Tern.

Bird Acoustic Sensors to record diurnal and nocturnal bird calls 24/7, filling data gaps for spring and fall migrant passerines and shorebirds, including threatened and endangered species.

Bat Ultrasonic Sensors to record calls of bats active in the area.

Underwater Hydrophones to record vocalizations of marine mammals including baleen whales.

Receivers to record species-specific information on tagged fishes.

Sensors to record waves and currents.

Sensors to record salinity, temperature, and water-level.

Data and Reporting Accessibility via ReMOTe

Remote Marine and Onshore Technology (ReMOTe) is Normandeau's secure data portal ( providing the ability to access, analyze, and visualize a variety of species information on a secure, user-friendly platform.


Data Types

Initially developed for Normandeauís bat acoustic studies and our high-resolution aerial imaging data, ReMOTe is also suitable for species data collected by other methods, including visual and acoustic data collected via commercial or client-specific methods. All data are stored at our secure data management center.


Access to data through ReMOTe is project-specific. Data access can be public, restricted, or a combination of both depending on client needs. Data visualizations and outputs are customizable depending on client needs.


As data are reviewed and processed, ReMOTe records all changes made by each analyst, thus ensuring total traceability and allowing easy and transparent tracking of progress and quality control. Identifications and data analyses are updated in real time as completed, making project tracking easy for both client and collaborators.


Data and metadata are displayed in the most appropriate format for the project purpose and type of data collected. Georeferenced image data may be displayed on an interactive map with associated species identifications, metadata, and tabular reports available at the click of a mouse.
