Yes, Sentinel-1 satellites can map icebergs. Sentinel-1 satellites are operated by the European Space Agency. The Copernicus Sentinel-1 radar mission uses artificial intelligence (AI) to map icebergs. AI can map icebergs 10,000 times faster than humans.
Sentinel-1 satellites can:
- Provide images of icebergs regardless of cloud cover and lack of daylight
- Observe the drift of icebergs over the Southern Ocean with around 1–3 d of temporal resolution and 10–40 m of spatial resolution
- Track Antarctic icebergs
- Correlate detections with Automatic Identification System (AIS) or Long-Range Identification and Tracking (LRIT) information broadcasts from ships to determine sources and prosecute offenders
- Transmit data relevant to oil spill monitoring in real-time
Monitoring Earth’s ice is vital to understanding where and how it is changing and to plan for the future. These regions are so remote and so vast that doing so is only possible through the use of satellites
Why do satellites monitor icebergs?
It is vital we monitor Earth’s ice to understand where and how it is changing and to plan for the future. These regions are so remote and so vast – Antarctica is 61 times larger than the UK – that doing so is only possible through the use of satellites
Can satellites see the ocean floor?
To date, ships have charted only a small fraction of the seafloor. But thanks to gravity, the ocean surface has broad bumps and dips that mimic the topography of the ocean floor. These bumps and dips can be mapped using a very accurate radar altimeter mounted on a satellite
Can satellites see pollution?
Satellite images help identify large areas of pollution caused by fires, dust or sand storms, volcanic eruptions, large industrial sources, or the transport of man-made pollution from other regions. Smaller sources, such as small industries or local roads won’t be visible in satellite images.
Can satellites see you?
NOAA satellites have the capability to provide astounding views of the Earth, but many people want to know if these satellites can see their houses, or even through their roofs and walls to the people inside. The answer is: no. Satellites differ greatly in the level of detail they can “see”.
The Sentinel-1 satellites are a constellation of two polar-orbiting satellites that provide all-weather, day-and-night imagery of Earth’s surface. They carry a C-band synthetic-aperture radar (SAR) instrument that has a spatial resolution of down to 5 m and a swath of up to 410 km. The satellites operate day-and-night and perform synthetic aperture with radar imaging.
The Sentinel-1 satellites were designed to provide spatial data for environment and security warranting, global economic and business growth. They can see at night and through clouds with millimetre accuracy when measuring elevation.
The first mission in the series, the Sentinel-1 constellation, includes twin satellites that were launched on:
- Sentinel-1A: April 3, 2014
- Sentinel-1B: April 25, 2016
As of December 23, 2021, Sentinel-1B is no longer able to acquire data. An anomaly related to the power supply cannot be repaired, and the satellite will be decommissioned.
There are even satellites that can not only track icebergs but can map the Antarctic in the merest blink of an eye. In fact, faster than that since a typical blink takes about 0.2 seconds but the Sentinel-1 satellites can map icebergs in just 0.01 seconds, that’s 20 times for every blink of an eye!
