Indian River Lagoon Research

A Mucked Up Lagoon

Lagoon Muck

Right in Florida Tech’s backyard is the Indian River Lagoon, home to more than 3,000 species of plants and animals that are suffering from a half-century of neglect and pollution. As more people have made the Space Coast their home and increased development and pressure on the lagoon, marine life has been decimated by a deadly chain reaction started from fertilizer run-off and waste water. The lagoon is now home to a massive build-up of muck, a thick mixture of nitrogen and phosphorus that resembles black tar. In some parts of the lagoon, the muck has reached epic proportions, up to 10 feet high, suffocating seagrass beds, a vital part of the lagoon’s eco-system. Muck is contributing to large scale algae blooms which consume massive amounts of oxygen, choking out marine life. Now, the lagoon is afflicted with massive die-offs fish, sea turtles, manatees and dolphins. Through concerted research efforts, Florida Tech faculty and students are developing solutions to the Indian River Lagoon’s dire situation.

“The distribution of muck has continued to increase in the lagoon and the release of nitrogen and phosphorus from muck sediments may have played an important role in fueling these algae blooms.”

Sustainability Professor Shows How to Have a Lagoon-Friendly Lawn

Professor Ken Lindeman is a huge proponent of native landscaping. So much so that he shares how he transformed his own lawn with Florida native plants. The goal is to not only to reduce water usage and run-off but also to skip using fertilizer all together. Fertilizer and freshwater run-off are some of the main [...]

Communication Majors Create Moving Documentary About Indian River Lagoon

by Lindsay Isaac The most biologically diverse estuary in North America is dying—and Florida Tech students are trying to save it. That became the premise of the 13-minute capstone documentary produced by seniors in Florida Tech’s communication program this semester, Dr. Johnson’s Lab.  I was the director of Dr. Johnson’s Lab, which traces the story [...]

Student Researcher Helping to Make Lawns Lagoon Friendly

The Indian River Lagoon (IRL) has been suffering from high nutrient inflows that include stormwater run-off, fertilizer and lawn clippings. These nutrients degrade the lagoon’s water quality which leads to the build-up of muck, algal blooms and consequently major fish die-offs. To combat these issues, the sustainability minor research project of ocean engineering student, Andrew [...]

Graduate Students are Building a Solution for the Indian River Lagoon

If you ask a team of ocean engineering students if they want to design and build a dredge to help the ailing Indian River Lagoon, it’s unlikely you would get a no from Florida Tech students. This is true for graduate students Leigh Provost, Hannah Grisanti and Ryan Christiansen. Ocean engineering professor Dr. Robert Weaver [...]

Help Heal the Indian River Lagoon at TechCon2017: September 29, 2017

Through the years, construction, pollution, over-harvesting, muck, algae blooms and a host of other factors, have conspired to taint the natural majesty of the Indian River Lagoon. But a committed group of scientists, engineers, coastal resource managers and educators has made combating these assailants their mission as members of the Indian River Lagoon Research Institute (IRLRI) [...]

Meet our Experts

Expert Group

A group of more than 20 faculty members with decades of scientific research experience related to the Indian River Lagoon have come together to form the Indian River Lagoon Research Institute (IRLRI). Collectively, Florida Tech scientists and engineers are developing solutions to the major issues plaguing the health of the lagoon, including muck and nutrients, lagoon flow, nutrient reduction, sediment loading, ecosystem recovery, policy and management, and engineering technologies. Part of the mission of the IRLRI also includes outreach and education to help the community and lagoon stakeholders understand the importance of IRL problems and their role in creating solutions. The IRLRI collaborates with numerous institutions and agencies along the lagoon with the common goal of improving the lagoon’s eco-system.

How you can make a difference

 

Oyster Icon

To help bring oyster beds back to the shores, the IRLRI’s Living Docks program invites local residents to turn docks and seawalls along the shores of the lagoon into homes for oysters. Participants hang mesh bags filled with used oyster shells from the sides of a dock or seawall and submerged into the water. The presence of the shells attract oyster larvae, which then propagate and grow. A single dock with 37 pilings—with an average of 32 oysters per piling—can filter about 21 million gallons of water per year.

There are many ways to help improve the health of the Indian River Lagoon, from adopting eco-conscience landscaping practices like reducing fertilizer usage, preventing grass clippings from going down storm drains and growing Florida-friendly native plants to simple things like picking up trash and after your pet. Little actions can go a long way.
