Effect of freshwater inflow on macrobenthos productivity in minor bay and river-dominated estuaries, FY02 : final report
MetadataShow full item record
This final report is written to complete the second of a planned five-year study that has the goal to determine the importance of freshwater inflow in maintaining benthic productivity in minor bays and river dominated systems. Minor bays are defined as those small bays that do not have direct freshwater inflow via a major river, but do have inflow from runoff or other indirect sources. Only a few rivers in Texas flow directly into the Gulf of Mexico, and these are also part of the subject study. The current project follows successful completion of a long-term study of large, or major open bays in Texas. The focus of the current final report is on South Bay Coastal Preserve. An assessment report for that ecosystem is planned within the current fiscal year. Hydrological and biological data are compiled to assess that system. Sampling was also continued for a long-term study of two river-dominated systems, the Rio Grande and Brazos River. Sampling was begun for a 2-year study of Christmas Bay Coastal Preserve. The current report goes into lesser detail for these continuing data sets because they will be subject to a fuller treatment in future.
