Transcript of Gowanus Canal DRAFT Research Notes on Thermal Mapping for finding old streams
Thermal Light Painting of the Gowanus Canal Can we find out if water temperature differences of industrial inflows and old streams can be mapped ?
Gowanus Canal
Manhattan
Gowanus Watershed
The Canal
Historic Landfilled Tidal Marsh
Manhattan
Gowanus Canal Superfund Site
Canal Gets a Million Gallons of Sewage A DAY
WHAT CAN WE DO ABOUT IT ?
STREAMS WE ARE MAPPING
ECOLOGICAL WATER CYCLE
URBAN WATER CYCLE
IT RAINS
WATER GOES INTO PIPE
INFILTRATION & STREAM RESTORATION
SOME WATER GOES INTO PIPE
NOT FOUND
FOUND WITH KITE & BALLOON MAPPING
WHY MAP BURIED STREAMS?
WHAT WE WANT:
WHAT ARE BEST SITES ?
The Gowanus Canal Conservancy

DENTONS SPRING RESTORATION
BROUWERS BROOK RESTORATION
SECOND AVE BIOSWALE
SECOND STREET SPONGE PARK
USING BALLOON CAMERAS TO MAP PLANTS & HISTORIC STREAMS
WANTS TO REDUCE SEWER OVERFLOWS AS PART OF ECOLOGICAL RESTORATION PLAN
BERGEN STREAM RESTORATION
Brouwers Brook Balloon Aerial July 2011
Mapping the historic streams of the Gowanus Canal
Are there clues in the water’s color ?
YES – DARKER MEANS FRESH WATER, MILKY = SEWAGE

Setting up the trial and error process of scientific inquiry for local issues
IS BERGEN STREAM MAYBE HIDDEN BEHIND A HOLLOW PART OF THE CANAL’S EDGE ?
BEING WARMED BY SOIL, WOULD THE OUTFLOW BE WARMER THAN THE OPEN WATER ?
