Altimetry data: To help fishermen, CATSAT provides maps of sea level anomaly from altimetry. Altimetric maps are especially reliable as they are unaffected by the presence of clouds.
Temperature data: CATSAT provides sea surface temperature maps that highlight oceanic fronts, upwelling and eddies, and homogeneous water masses. Cold water is represented by deep blue while red-orange zones correspond to warmer water. Some pelagic fishes are known to move along the fronts, often feeding on the cold side.
Color data: Most ocean features have a clean signature in color maps, including oceanic fronts and upwelling and eddies. Phytoplankton concentration is indicated in red for high concentration: fish move to such areas to hunt and feed.
Marine meteorology data: This standard meteorological information is based on three parameters, supplied by the European Centre for Medium-Range Weather Forecasts (ECMWF), including sea level atmospheric pressure, wind direction and force and wave height.
Subsurface temperature: CATSAT service provides data from oceanography models (including data from MERCATOR project) taking into account satellites and in situ data measurements of the Ocean. These maps provide sub-surface information, at five depths 50, 100, 150, 200 & 300 meters deep.

CATSAT is a worldwide and round the clock, easy-to-use, onboard satellite service to help fishing.

Ocean-observing satellites and marine meteorology can help fishermen to:

  • Locate favorable fishing grounds
  • Reduce operating costs
  • Improve safety during fishing operations
  • Meet their quotas more efficiently

CATSAT is geared towards providing ocean data in near-real time for fisheries that support temperature-sensitive species such as:

  • Purse Seiners
  • Long Liners
  • Trawlers

CATSAT offers oceanographic data acquired by satellites and marine meteorology data, including:

Altimetry/Sea Level Anomaly Maps (SLA):
This new type of observation map, designed for the fishing industry, indicates the location of ocean eddies, fronts and associated currents, which are generally thought to be good fishing grounds.

Sea Surface Temperature:
This information is widely used by fishermen to locate thermal fronts and areas of strong gradients. It is very useful for pelagic fisheries.

Ocean Color:
Ocean color illustrates phytoplankton concentration of upper ocean. Fish often gather to feed in areas rich in phytoplankton.

Weather Forecasts:
Each day atmospheric pressure, wind, and wave height are forecast for the next seven days. These data allow fishermen to increase safety and better plan operations at sea.

Subsurface Temperature:
These maps, which are designed from oceanographic models, provide sub-surface information, down to 300 meters deep. It is very useful for long liner to moor their siding lines at the right depth.

WeeLee International has teamed up with the French company CLS (Collecte Localisation Satellites) to be the exclusive distibutor in Taiwan for CATSAT services.

Please note that WeeLee International and CLS are wholely independent companies in respect to each other.
