This is just one video about the State of the Gulf from Texas Parks and Wildlife. I chose this video because it contains a concise explanation of sea rise, as well as migration northward of fish and flora in Texas. The data is from routine samplings conducted by Texas Parks and Wildlife since 1974.
The entire series of videos are available for viewing at Texas : State of Water and YouTube. The entire film may be viewed on PBS.
