FAO: Inland fisheries are an increasing
contributor to global capture
![Page 32: USGS Great Lakes Science Center Research & …...U.S. Department of the Interior U.S. Geological Survey USGS Great Lakes Science Center Research & Examples of Remote Sensing Applications](https://reader034.fdocuments.net/reader034/viewer/2022042416/5f3120299ff0b34ffd6e70cc/html5/thumbnails/32.jpg)
• Inland capture fisheries also believed
to be underestimated; diminishes their
importance relative to marine harvest.
• Inland fisheries provide important
ecosystem services (esp. in developing
countries):
protein-rich food securities
employment
commerce
recreation
![Page 33: USGS Great Lakes Science Center Research & …...U.S. Department of the Interior U.S. Geological Survey USGS Great Lakes Science Center Research & Examples of Remote Sensing Applications](https://reader034.fdocuments.net/reader034/viewer/2022042416/5f3120299ff0b34ffd6e70cc/html5/thumbnails/33.jpg)
Goal: Develop less biased estimate of
global inland fisheries harvest.
Hypothesis: Lake productivity and climate
are strong predictors of fish harvest.
Strategy: 1) Build statistical “training”
models relating remotely sensed data
(e.g., productivity, climate, lake size) to
known fish harvest. 2) Extrapolate.

MODIS vs. MERIS
MODIS and SeaWiFS are the
US “workhorses” for water color
remote sensing
─ 1 km native resolution
─ Global product 4 km resolution
Full-resolution (300 m) MERIS
data became available through
NASA late last fall
Multi-mission reprocessing has led to high consistency
between SeaWIFS/MODIS/MERIS/VIIRS OC products
NASA has found that MERIS estimates tend to be lower
than MODIS in eutrophic waters, but without a robust in
situ dataset, they can’t determine which is more correct 38

Observation: Sites at which lake trout deposit eggs are
cleaner than substrate on surrounding sites (Drummond
Island acoustic telemetry study)
Question: Can satellite imaging be used to identify potential
lake trout spawning sites by locating ‘clean’ areas on reefs?

Promising preliminary results:
• Accurately identified differences in algal density between 0 and 60% cover
using substrate radiance – above 60% cover was difficult to distinguish
• Classified 60 sites on two reefs as spawning site or non-spawning site using
logistic regression: (Spawning ~ pre-spawning radiance + change in radiance)
Correct assignment
approximately 85% of
the time

Changes in terrestrial water between 2002-2012 by NAWQA glacial region, derived from GRACE data. The change in mass reported for each cell represents the difference between the mass measured in that month and the average mass for the period of Jan 2004-Dec 2009.
Preliminary analysis for demonstration only:
GRACE land-data were processed by Sean Swenson, supported by NASA MEaSUREs Program and are available at http://grace.jpl.nasa.gov
