Cetacean movement modeling

Whale "math" resources! These tools can help forecast how a cetacean may move through the Salish Sea, and therefore when and where it may be encountered next...

  1. Salish Sea travel time spreadsheet (Google sheet; metric units; input any decimal speed in km/hr, but currently assumes 6-7 km/h for both SRKWs and Bigg's killer whales) Screenshot 2025-02-06 at 1 21 49 PM

  2. SpyHopper.ca "Whale math" travel time tool (map layer; nautical units; input speed in knots with three choices: slow=3, ave.=4.5, or fast=6 [5.5, 8.3, 11.1 km/h, respectively]) Screenshot 2025-02-06 at 1 00 08 PM

  3. HALLO project's forecast models for SRKW movement (Peter Thompson in 2024-5; Teng-wei Lin in 2023-25 (2024-25) | Marine Randone's web page and publication (2022))

  • Other species?

    • Anything for humpbacks in the Salish Sea? (since they are most commonly struck within Puget Sound)
    • Harbor seals (e.g based on telemetry tag observations?)
    • Porpoise distribution probability model based on zooplankton layers of the oceanographic models?
  • Habitat models

    • Humpback density surfaces from ERMA
    • Sounder gray whales?
    • Atlas of pinniped haulouts?
  • Integrated models & frameworks

  • Human population status & growth models
    • Most current population estimates:
      • SRKW range: ??
      • Salish Sea region: 9 million in 2019
      • Puget Sound: ??
      • Central Puget Sound: 4.3 million in 2020
    • Human population of the Salish Sea Region GIS storymap (Salish Sea Atlas, Aquila Flower, 2021) -- 1990-2030:

  • Puget Sound Regional Council's Vision 2050 (30y projection from 2020) includes this plot of past and projected human population (and jobs) for counties in "central Puget Sound"-- 1970-2050:

Mapping efforts

Public sources of bathymetry data or map tiles?

Shoreline imagery

Marine Protected Areas & spatial regulatory information
