Finding a new job can be very difficult, having the right resource can help. GIS jobs clearing house is that resource. They have a long list of jobs and resumes stored in their databases as well as resources for both the job seeker and potential employer.

One class of job openings that they list is benthic mapping. Benthic mapping is the mapping of the ground beneath a body of water. It doesn’t matter if it is a lake, river or ocean floor. This mapping process is especially important for the seabed.

People call the ocean floor the last frontier because it isn’t fully mapped and explored. Every year new species are found living in the ocean or on its bottom. The entire ocean is an amazing habitat full of biodiversity. The ocean floor is no less an amazing habitat. In the past, the accepted theory was that the deep ocean floor was barren, but using benthic mapping scientist found out that there were habitats that supported life.

Mapping is done by sending sound waves into the water. The bottom then bounces the sound back up. The length of time that it takes for the sound waves to return shows how deep that particular area is. It also reveals the makeup of the area. Lateral mapping is done by broadcasting the sound waves sideways from a drone or buoy dragged along behind a boat or ship. This sideways sonar reveals how far particular features are from one another.

One of the primary uses of benthic mapping is to measure the effects that man has had on the seafloor. There are many ways that the actions of humans has affected the ocean floor. Run off from pollution, increased silting and the use of destructive ground or drag fishing all change the bottom of any body of water negatively. The importance of mapping the seabed in this case is to point out where the at-risk locations and populations are. GIS jobs clearing house comes in handy here to find jobs working on this kind of benthic mapping.

Drag net fishing is when the fishermen drag nets along the bottom of the ocean. The nets have weighted bottoms to keep them own. As the nets are dragged along, they not only catch fish, they also scrape and move things on the bottom. Benthic mapping measures the damage done by this kind of fishing. The resulting maps have been used to limit the areas where this kind of ground fishing is allowed.

Mapping the bottom of any body of water whether it’s the ocean, the river or lakes is important because it is only with the knowledge that gained from that mapping that measures can be taken to protect the vast biodiversity that shows up on the bottoms. Finding the right job to get in on that mapping can be difficult, especially for those graduates who are just out of school. Looking at the right place, like GIS jobs clearing house, is the way to start. They have the resources available to help people looking for work as well as the employers looking to hire new GIS professionals.
