INCOIS launches three warning systems for fishermen
The swell surge forecast system has been designed to predict swell surges, which cause damage to the boats and nets of the fishermen.
The Indian National Centre for Ocean Information Services (INCOIS) has launched three ocean-based advanced warning systems- Swell Surge Forecast System (SSFS), Algal Bloom Information Service (ABIS) and the Small Vessel Advisory and Forecast Services System (SVAS).
Swell Surge Forecast System
The swell surge forecast system has been designed to predict swell surges, which occur along the Indian coast, especially on the western coast. The waves are created due to distant weather systems and they take place without any noticeable change in the local wind or the coastal environment. The Swell Surge Forecast System will reduce the damage and losses incurred by the fishermen and alert them well in advance about the swell surges.
What are Swell Surges?
The swell surges are surface gravity waves and not the normal wind waves. The swell waves originating from the Southern Indian Ocean frequently cause damage to the coastal region. They are like flash floods and cause damage to the boats and nets of the fishermen. They are often mistaken for tsunamis.
Small Vessel Advisory and Forecast Services System
The Small Vessel Advisory and Forecast Services System has been designed to improve the operations of small marine vessels, especially fishing vessels. The system will warn the users regarding the potential zones where the small vessels are likely to overturn. The advisory issued by the system is only valid for small vessels with a beamwidth of 7 m. The limit covers most fishing vessels used by nine coastal states and union territories.
The Small Vessel Advisory and Forecast Services System is based on the Boat Safety Index (BSI), which is derived from wave model forecast outputs including wave height, wave steepness, directional spread and rapid development of wind at sea, which is boat-specific.
Algal Bloom Information Service (ABIS)
The Algal Bloom Information Service aims to prewar regarding the harmful algal blooms, which can cause damage to the coastal fisheries and cause respiratory problems among the coastal population.
The algal blooms are a major concern for the coastal population due to its damaging effects on the marine life, fishery sector and water quality. The Algal Bloom Information Service will help track the increasing frequency of algal blooms.
The service aims to benefit fishermen, ecologists, marine fishery resource managers, researchers and environmentalists. It will also provide almost real-time information regarding the spatio-temporal occurrence and spread of phytoplankton blooms over the North Indian Ocean.
What is INCOIS?
The Indian National Centre for Ocean Information Services is an autonomous body that functions under the Union Ministry of Earth Sciences. Besides launching these three alert systems, the body has provided several free services for the users in the coastal region including fishermen.
