Book Description
Estuaries are defined by mixing of river and sea water, thus freshwater inflow is a key driver of estuary ecosystem structure and function. While there is much concern about water quality, there is much less about water quantity. As water is diverted for human use, less is flowing to the coast, which threatens estuary ecosystems. Some jurisdictions are now setting inflow standards, but there is no consensus on how to identify how much freshwater an estuary needs. There is a climatic gradient along the northwestern Gulf of Mexico coast and estuaries vary from hydrologically positive to neutral to negative, and this makes the Texas coast the ideal place to study how ecological processes vary with freshwater inflow. An estuary comparison approach is used in this open access work to examine hydrology, circulation, salinity, nutrients, carbonate, dissolved oxygen, plankton, nekton, benthos, and habitat dynamics and responses across varying hydrological regimes.

Book Description
In response to the Texas Water Code 16.058(a), the Texas Water Development Board (TWDB) and the Texas Parks and Wildlife Department (TPWD) have prepared a report on the effects of freshwater inflows on Texas bays and estuaries. Two main themes are examined in the report: demonstrating the effects of freshwater inflows on living and non-living components of estuarine ecosystems; and presenting a methodology for assessing the freshwater inflow needs of Texas bays and estuaries that satisfies the requirement on maintaining an ecologically sound environment and the productivity of fish, shellfish, and other estuarine life.

Book Description
This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

Book Description
Understanding spatiotemporal variability in freshwater inflows to the bays and estuaries along the Gulf of Mexico is critical for water resources management to maintain the health of the ecosystem and marine life. The objective of this study was to assess linkages between climate teleconnections (e.g. El Nino Southern Oscillation [ENSO], North Atlantic Oscillation [NAO], and Pacific Decadal Oscillation [PDO]), precipitation, and freshwater inflows to the Gulf of Mexico. Seasonal Trend Decomposition using LOESS (STL) analysis was used to decompose monthly precipitation and freshwater inflows (1941-2015) to each bay and estuary, isolating long-term variability, and comparing it to ENSO during warm and cool PDO phases and NAO. Results show that there are moderately strong positive correlations between ENSO and precipitation (R = 0.37 to 0.7) with mostly higher precipitation during El Nino and lower precipitation during La Nina. These correlations were weakened during PDO warm phase (R = 0.16 to 0.41) and amplified during PDO cool phase (R = 0.66 to 0.8). Temporal variability in precipitation was linked to bay and estuary freshwater inflows, showing high flows during El Nino and low flows during La Nina. Additionally, there are moderately strong positive correlations between NAO and freshwater inflows to two of the 10 bays/estuaries in the northeast (Sabine-Neches and Trinity San Jacinto, R = 0.45 and 0.41). These correlations tend to occur within the year of the driving conditions in the Pacific and Atlantic oceans. Identifying these linkages and the corresponding response times can help predict and manage the hydrologic response to wet and dry climate cycles linked to climate teleconnections along the Texas Gulf Coast to help protect and maintain the health of the vital estuarine environments
