TIDE: Tracking and Intelligence for Dive Expeditions — TIDE: Tracking and Intelligence for Dive Expeditions

A coordination platform that maps reef survey coverage to prevent duplicate efforts and wasted resources, so organizations can allocate resources to sites that need it most.

SoundScape — SoundScape

An interactive simulation of ocean noise pollution where you reroute shipping lanes in real time to protect whale migration paths.

U-HALK: Ultrasonic Harmful Algae Killer — U-HALK: Ultrasonic Harmful Algae Killer

Algal blooms, caused by the accumulation of agricultural fertilizer from runoff, is a main contributor to harming environmental heath. Our project kills algae with a rotating ultrasound system safely.

SENS Pod: Submersible Environmental Networked System — SENS Pod: Submersible Environmental Networked System

The SENS Pod is a buoy network for coral reef ecosystems, monitoring temperature, salinity, pH, and turbidity in real time: using machine learning to predict reef health and guide ocean conservation.

PlasticFlow — PlasticFlow

Visualizing the invisible threat in our oceans. PlasticFlow is a data visualization platform that maps global distribution of microplastics and their movement by analyzing NOAA and NASA datasets.

SCUDA: Scuba-sign Capturing User-interface Data Analysis — SCUDA: Scuba-sign Capturing User-interface Data Analysis

A wearable IMU-based sign language recognition system that captures hand gestures with trajectory tracking. Users record signing movements and label gestures, which can be fed to ML models.

Pale Watch — Pale Watch

A low-cost ocean monitoring system that detects environmental threats like pollution, temperature shifts, and obstacles to help protect coral reef ecosystems.

AI Carbon Sink Predictor — AI Carbon Sink Predictor

Predict the ocean’s carbon absorption anywhere in the world to fight climate change.

Okeanos — Okeanos

Okeanos aims to help solve ocean pollution. We built a novel dataset on the trends of pollution and animal patterns by collecting data from millions of ships and aggregating their camera and GPS data.

GRIME (Garbage River Interception & Modeling Engine) — GRIME (Garbage River Interception & Modeling Engine)

The plastic in rivers knows where its going. Now you do too.

BioSonar — BioSonar

BioSonar classifies whale species from raw ocean audio using a fine-tuned ResNet-34 CNN

Fish Identifier — Fish Identifier

Save fish. Save the oceans.

Ocean Impact Tracker — Ocean Impact Tracker

Our project focuses on following a piece of trash through simulated ocean currents, mapping how it affects the ecosystems it passes through.

Ocean Awareness project — Ocean Awareness project

Pollution spreads fast. Awareness spreads faster.

G.O.O.P: Growth-Optizing Organic Polymer — G.O.O.P: Growth-Optizing Organic Polymer

Is it possible for organisms to live on trash islands? We made a simple tool that can help researchers understand the makeup of the plastisphere.

OceanEcho — OceanEcho

Every second, noise pollution harms marine life, leading to OceanEcho, an interactive AI that answers users via EchoBot and uses noise-cancellation AI to bring back the ocean’s natural soundscape.

HydroHub Plan — HydroHub Plan

Optimize emergency hub placement across the U.S. to minimize travel time and maximize coverage for communities at risk from floods, hurricanes, and coastal storms.

OceAi — OceAi

oce.ai - understand the ocean. AI-powered marine intelligence. Real-time fishing predictions, ocean policy insights, and research: all in one place.

AcidWatch 3D — AcidWatch 3D

90% of marine life depends on ocean pH, which has dropped 26% since industrialization. AcidWatch 3D maps that crisis: drag through time and watch ecosystems collapse or recover.

The Cost of the Catch — The Cost of the Catch

A strategy game that focuses on how overfishing can impact ecosystems and fishermen by bringing awareness to the player, as their careless actions result in harm to aquatic life and ecosystems.

Guided Ocean Observation and Navigation Exploration Rover — Guided Ocean Observation and Navigation Exploration Rover

GOONER is a submersible robot that monitors coral reef health using sensors and cameras while detecting invasive species with a real-time YOLO computer vision model.

ShoreLight — ShoreLight

ShoreLight maps NASA satellite data against years of sea turtle nesting record to quantify light pollutions actual impact on marine life and model how dark-sky policies can save marine animals.

OceanRoute — OceanRoute

OceanRoute visualizes how commercial shipping routes overlap with whale migration paths and calculates a real-time disturbance score. It also simulates a live route optimization.

ReefQuest — ReefQuest

As environmental changes push marine species to isolated locations, ReefQuest serves as a way to simultaneously provide more marine data while engaging people to explore and photograph marine life.
