Thermal infrared data collected at Hen Cove, Pocasset, Massachusetts, August 2022

Published by U.S. Geological Survey | Department of the Interior | Metadata Last Checked: January 27, 2026 | Last Modified: 2025-02-03T00:00:00Z
These thermal infrared data (images and radiometric video) were collected with a FLIR T540 Thermal Camera with the following manufacturer specifications: Resolution: 464 × 348 pixels Spectral range: 7.5 - 14 µm Thermal sensitivity: less than 50 mK, 14° @ 30°C (86°F) Accuracy: ±2°C (±3.6°F) or ±2% of reading. All temperature measurements should be interpreted as 'apparent' as the thermal parameters of the camera have been set to assumed values for water and may not apply to reflected radiation off the water surface or other types of materials such as grass and sand. For the identification of possible groundwater discharge zones, relatively cold areas during warm days are investigated further with direct measurements. These data are for demonstration purposes only. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by the U.S. Government
