Sofar Spotter
The smart buoy that delivers realtime weather data from anywherein the ocean.
Real-time ocean data is sparse and notoriously
difficult to collect. Spotter changes that. Thisturnkey marine sensing device gathers wave,
wind, sea surface temperature, and barometricpressure data, and delivers insights via Sofar’s
Spotter Dashboard and API. Spotter gives you
instant, accurate visibility of ocean conditions.
Real-time data, OTA updates, sharing, & API

Compact, Portable, and Easy to Deploy

24/7 satellite and cellular connectivity provides access toreal-time weather data and system updates at any time.
Share data through the Spotter Dashboard, use the API toconnect your data to wherever you need it, or use ournative ESRI map layer. Cellular-enabled over-the-air
firmware updates mean your Spotter is always getting
new features and new capabilities.

Roughly the size of a basketball, Spotter can be shipped
anywhere around the world, carried by hand, and deployedfrom any size vessel. Every Spotter comes with 1 year ofIridium satellite data credits included, so it is immediately
ready to deploy.

Data Partitioning

Spotter collects 3D displacement timeseries, and calculates the wave spectrum,
which is stored onboard and can betransmitted through the dashboard. In
addition, you receive updates for:Spotter comes equipped with a compact,
digital temperature sensor to provide
high-fidelity Sea Surface Temperature(SST) measurements. The sensor ismounted in an insulated stainless steel
penetrator to provide excellent thermal
contact with the water and is rated for
0.1ºC absolute accuracy and 0.02ºC
resolution.

In addition to the standard bulk
parameters, Spotter can provide thesame parameters over ‘sea’ and ‘swell’
wave partitions.

The barometer measures atmosphericpressure at the sea surface with rated
initial accuracy of + / - 1 mbar between
0°C to 50°C at an operating range of 700
to 1100 millibars. Accuracy is relative tosingle-point calibration reference.
Accuracy drift of up to 1mbar/year.

Spotter Success Stories

Protecting Beluga Whales in
the Canadian Arctic

Powering Wave Energy
Innovation in Gibraltar

Supporting Sustainable
Aquaculture in Chile

This long-term program uses coastal
observatories (seabed moorings withacoustic recorders and oceanographic
sensors and weather stations) toinvestigate the influence of changing
environmental parameters (waves,weather, ice, and coastal erosion) on
beluga habitat use, water column
biogeochemistry, and underwater noiseand vessel impacts.

“Spotter provides integral information as
it allows us to conduct accurate
measurements of wave height, period
and direction in the exact location of ourwave energy power station, thereby
providing us with the possibility toperform a high accuracy comparison
between the wave characteristics and theenergy produced,” said Marina Gurevichof Eco Wave Power.

Among several efforts to understand therelationships between aquaculture
production and the marine environment, areal-time monitoring network ofenvironmental variables is underway atsalmon farming sites around Southern
Chile. This network aims to promotesensible management of aquaculture
production and coastal risk alert systems
through large scale data analysis.

Solar-powered

Rugged design

Spotter dashboard

The combination of solar panels and arechargeable battery means that you
never have to worry about running out ofpower. Spotter is self-contained, lowmaintenance, and always ready to collectdata.

The ocean is a rough place. Every part of1.
Spotter is built to withstand the harshest
ocean elements in any weather condition,anywhere on our planet. Spotters have
logged over 10 million ocean hours.

The Spotter Dashboard and API provide
access to real-time and historical data.
The dashboard enables you to change
your Spotter’s settings from anywhere in
the world, set up alerts for weather
conditions, and get notified if yourSpotter is outside of its geofence.

Smart Mooring is the underwater extension of our Spotter platform. It
anchors Spotter to the seafloor and expands its sensing capabilities
beneath the surface. Simply deploy your Spotter and Smart Mooring
devices and start gathering underwater insights in real-time.
Powered by Spotter. Spotter is thepower and data connectivity hub for
Smart Mooring. All subsurface
insights are accessible in real-time
via the Spotter dashboard and API.

Customizable. Need a fully custom
Smart Mooring solution? Using theBristlemouth open hardware interface,
we’ve worked withpartners to implement novel sensor
integrations and configurations.
