Overview
Bright Dyes act as a coloring label on each drop of water. As that water or liquid travels, it can be identified at each point on its travel until it reaches extreme dilution. It may be detected visually, by ultraviolet light and by appropriate fluorometric equipment. The dyes selectively absorb light in the visible range of the spectrum. They are fluorescent because, upon absorbing light, they instantly emit light at a longer wavelength than the light absorbed. This emitted (fluorescent) light goes out in all directions. Most common fluorescent tracers are compounds that absorb green light and emit red fluorescent light.
Absorption Resistant
FWT red dye is resistant to absorption on most suspended matter in fresh and salt water. Compared to Bright Dyes FLT Yellow/Green products, FWT Red is significantly more resistant to degradation by sunlight and, when used in fluorometry, stands out much more clearly against background fluorescence.

Restoring North Texas Streams to Historical Flows
North Texas is one of the fastest-growing regions in the state, an area that is expected to face increasing water needs. In order to meet these demands, the Upper Trinity Regional Water District ( UTRWD ) is building Lake Ralph Hall near Ladonia in southeast Fannin County, Texas. The lake has been in the works since 2003, with construction finally beginning in 2021. The population of the UTRWD is expected to grow 5-fold over the next 50 years, leading to increased water use. Ed Motley, Program Manager with the UTRWD stresses that even with conservation and reuse, new sources like Lake Ralph Hall are essential to meeting near-term and long-term water needs to support regional growth.

Science for Science’s Sake: Monitoring Ocean Energy Availability and Gulf Stream Dynamics
Scientific research often begins with a question, sometimes driven by a specific goal or application, but many scientists believe in science for science’s sake. Marine environments and physical dynamics like the Gulf Stream are popular fields of research due to their complexity and importance, presenting a unique opportunity to learn more about previously unexplored phenomena. Environmental researchers, in particular, see the value in these ecosystems, but many also grew up with a passion for the natural world, and choosing a field that allows them to interact with and learn about the environment around us is an easy choice.

Research in the Reserve: Promoting Interdisciplinary Conservation at the Great Bay National Estuarine Research Reserve
On an early winter day in 1973, a helicopter buzzed over Durham, New Hampshire, just a few miles from the Atlantic Ocean. One of the helicopter’s guests, oil magnate Aristotle Onassis, owner of Olympic Refining, looked east of town and saw what he hoped would become the world’s largest oil refinery. Instead, he saw the Great Bay; thousands of acres of green coastal forest, mud flats, salt marshes, and estuarine tidal waters stretching over the land toward New Hampshire's small Eastern coastline. Onassis likely also saw a group of Durham residents staked out on the bay’s coast, ready for him to pass overhead. While out of place in the natural setting, an obvious message was spelled out in red paper: “Not Here.
