Data Collection
Camera System
PLACE HOLDER FOR APEM SLIDES
• Spring survey was flown with the Shearwater III camera system.
• Camera performed well
Survey Timing
The Spring survey was targeted to capture data during the first few weeks of May
The survey started on the 4th of May and was completed on the 21st of May
There were a total of 9 flying days to complete the survey
WEA Survey Design
OPA Survey Design
Flight plan is currently split between nearshore and offshore areasNearshore area
Access to the restricted area around JFK was granted so all survey lines across the OPA were captured at 1.5cm
No transect lines for the OPA were split during data collection
OPA Survey Design
Weather and Survey
Date (2017) Action
May 4 5 lines of the OPA were flown
May 7 2 lines of the OPA were flown
May 92 lines of the OPA, 4 lines of the nearshore East area and 2 lines of Montauk Bay were flown
May 10 2 lines of the OPA and 4 lines of the nearshore West area were flown
May 11 6 lines of the OPA were flown
May 16 28 lines of the WEA were flown
May 19 6 lines of the OPA were flown
May 20 2 lines of the OPA were flown
May 21 6 lines of the OPA were flown
• Weather conditions were fairly favourable although the survey crew did experience some periods of poor weather during the survey period
Images captured
Total images captured:WEA ~ 26,000OPA ~ 445,000
From this we anticipate analyzing:WEA ~ 13,000OPA ~ 350,000To achieve 10% WEA coverage and 7% OPA coverage
Image Analysis Progress
Total images screened so far:WEA ~ 0OPA ~ 40,000
Percentage of images screened:WEA – 0%OPA ~ 11%

Marine Mammals: ID Success
Downward sensors “see” through water column more effectively than angled views
More animals “observed”Depth potentially obscures characters required for identification

Discussion:
Do we want to change anything?
Seasonal Surveys Months (Purpose)
SummerJuly/August (fin, and humpback whales, turtles, shearwaters and gulls)
FallOctober/November (northern gannet, red-throated loon, black-legged kittiwake, jaegers and skuas)
Winter February/March (beaked whales, alcids)
SpringApril/May (right and sei whales, roseate tern, red phalarope)
Are there areas that need more detail?Is the timing appropriate?
