Seeing Seagrass in Real Time: How Researchers Use Seavu for Marine Habitat Studies

  • Read Time: 4 mins

Introduction

Seagrass meadows store carbon, support biodiversity, and protect shorelines — yet they remain some of the hardest ecosystems to study. Traditional fieldwork often meant lowering a camera, hoping for clear imagery, and checking the footage hours later.

With Seavu’s live underwater viewing technology, researchers can now see their results in real time, improving accuracy and efficiency in the field. The Seavu Seeker Marine Kit has become one of the most widely used seagrass research underwater camera systems in the world, helping scientists capture live data beneath the surface while reducing the need for large vessels or complex setups.

How researchers mount the Seeker Marine Kit

Many teams mount the Seavu Seeker Marine Kit on the square metal rigs they already use, often called quadrat frames. These frames provide a consistent scale and perspective for coverage and density measurements. With live view on a phone or tablet, researchers can align the view inside the frame, confirm focus and lighting, and capture images that meet protocol without redeploying.

Why live view matters for seagrass studies

  • Fewer missed shots and fewer redeployments
  • Precise alignment for spatial analysis and mapping
  • Real time checks for clarity, lighting, and composition
  • Safer and more efficient fieldwork in changing water conditions

Seavu connects popular action cameras to their native apps under water. Teams use GoPro Quik or DJI Mimo for live view, control, and recording, just like on land. For signal behaviour in water, see this explainer from NOAA.

The Seeker Marine Kit

At the heart of the Seavu system is a simple but powerful idea — extending your camera’s WiFi signal underwater.
While WiFi and Bluetooth can’t travel through water, Seavu’s custom system bridges that gap with purpose-built hardware.

  1. Seavu transmitter – captures your camera’s WiFi and Bluetooth signals below the surface, keeping the link alive even when the camera is fully submerged.
  2. Custom low-loss tether – carries the signal through the water column to the receiver on the surface, engineered for minimal signal loss and full flexibility.
  3. Seavu receiver – sits safely above the surface, rebroadcasting the signal wirelessly to your phone or tablet in real time.

The result is a stable live feed, with full camera control and real-time recording — all through the standard GoPro Quik or DJI Mimo apps you already use. There are no cables between your phone and camera, no external power boxes, and no fragile ports to worry about — just smooth, reliable underwater connectivity.

Whether the Seeker is mounted on a fixed rig, pole, or the DeepScope towing frame, this system gives you instant visual feedback and precision control in saltwater environments.

Built for Marine Conditions

  • Purpose built tether that is flexible, marine proof, and designed for long distance signal integrity
  • Versatile mounting options that fit poles, rigs, burley pots, and custom frames for stable positioning
  • No hard connections to the camera or phone, which reduces corrosion risk
  • Future proof design that works with the latest GoPro and DJI Action cameras

Introducing the Seeker DeepScope Rig

For surveys that need smooth movement and angle control, the new Seeker DeepScope Rig brings a stabilised, hydrodynamic design to live underwater viewing. Twin fins give balance and smooth motion. The adjustable mount lets users set the camera to look down, up, forward, or back for flexible transects and habitat passes.

  • Controlled towing over seagrass meadows for transect work
  • Benthic and reef edge mapping with consistent perspective
  • Species behaviour documentation and outreach filming
  • Optional lighting for deeper or low light surveys

Why Seeker and DeepScope are different

The Seeker Marine Kit and DeepScope Rig are compact, easy to use, and require no power beyond your camera and phone or tablet battery. They are also affordable. Most tow rigs used in research are big, heavy, and expensive, and they usually need a large research vessel. With Seavu you can deploy from a small boat and still capture stable, clear footage in real time.

  • Compact and light for quick deck handling
  • Easy to use with simple set up and live view
  • No external power required beyond camera and phone or tablet battery
  • Affordable system that fits real field budgets
  • Deploy from a small boat, not only a large vessel

Trusted by researchers worldwide

From the Australian Institute of Marine Science and CSIRO, to TropWATER at James Cook University and universities around the world, Seavu systems support long term monitoring and field campaigns. The marine proof, plug and play design helps teams focus on science rather than setup.

Final thoughts

Whether mounted to a stationary frame or towed with DeepScope, Seavu delivers clear, live underwater vision that improves data quality and field efficiency. The Seeker Marine Kit and DeepScope Rig help researchers see more, learn more, and protect more.
