Marine Ecosystem Research Platform

Tiny Sea Simulation

Model how climate change reshapes marine food webs. Run multi-year ecosystem scenarios, track species across three trophic tiers, and export rich CSV datasets for analysis. It all runs on your own machine.

Getting Started

1
Download

Grab the Windows or macOS build above.

2
Unzip

Extract the downloaded archive to a folder of your choice.

3
Run

Launch the app. On macOS, follow the setup guide to allow the app on first open.

4
Simulate & Export

Configure scenarios, run them, and export CSV data for analysis in R, Python, or Excel.

macOS users: because the app is distributed outside the App Store, you'll need to allow it in System Settings on first launch. The setup guide walks you through it step by step.

About This Simulation

Tiny Sea is a scientific research platform developed in collaboration with marine biologist Brian Helmuth to study climate-change impacts on marine food webs. It models a complete ecosystem with realistic temperature dynamics and predator-prey interactions, generating data on how species adapt (or fail to adapt) to changing conditions.

Ecosystem

  • Marine species across 3 tiers
  • Thermal variants per species
  • Predator-prey dynamics
  • Arrhenius thermal performance

Temperature Model

  • Seasonal cycles
  • Climate warming trends
  • Interannual variation
  • Daily weather persistence

Research Output

  • Per-day population data
  • Per-species metrics
  • Aggregate & bulk summaries
  • R-compatible CSV export
