Context Mapping for Finding Fossils

Paper

Satellite imagery can provide geologic context for scientific discoveries on the ground, such as sample location mapping for fossil discoveries. A new study led out of McGill University by Cortés et al. (2021) details the discovery of fossils in central Colombia that represent a new genus of ichthyosaur—large, long-extinct marine reptiles. Dubbed […]

Capturing Illegal Sand Mining in PlanetScope Imagery

Paper

Illegal sand mining is running rampant in the world due to the need for river sand as a binder in making concrete. Desert sand isn’t suitable for this purpose due to its shape. This illegal activity had led to the deaths of journalists, farmers, miners, and more, as well as causing ecological […]

The Effects of Greenspace Exposure on Childhood Development

Paper

Multiple studies have found that exposure to “greenspace” such as parks and forests has benefits to early childhood development. Some of these benefits include fewer behavioral problems, improved memory, and even better academic performance. However, the root explanations as to why these benefits happen are still not entirely clear. A new study […]

Mapping Arctic Landscape Change from Permafrost Thaw

Paper

Permafrost is defined as ground that remains below freezing for multiple years in a row. This frozen ground is hard as concrete. However, rising temperatures from climate change are leading to thawing of this permafrost, impacting local ecosystems and infrastructure. Thaw also results in the release of significant amounts of methane into […]

Monitoring Walruses from Space

Paper

Above Image: Point Lay, Alaska research site @ 2021, Planet Labs, Inc. Please note that walruses may not be present in this image, but can be seen in the referenced research paper. Walruses are coming ashore along the coasts of Alaska more frequently and in increasing numbers due to the decline in […]

Estimating River Flow with PlanetScope Data

Paper

Past studies have explored the use of flowing ice debris to estimate stream velocity with Planet data. However, tropical rivers pose a distinct challenge, due to high cloud cover and turbidity. Adriano Junqueira, of São Paulo State University, led a team to deploy a novel approach in the Araguaia River watershed in […]
