Farming in Ancient Lake Agassiz

- About 15,000 years ago Lake Agassiz covered southeastern Manitoba and much of the surrounding region. - The lake began draining ~12,000 years ago and left a thick, nearly flat deposit of nutrient-rich silt and clay that now supports productive farmland. - The Dominion Land Survey’s one-square-mile grid (late 19th century) still defines field, road, shelterbelt, and drainage layout. - An ISS astronaut photograph (April 19, 2026) shows snow-covered, rectangular farm patterns near Lake Winnipeg and cottage clusters around Gull Lake.

NASA Satellites Uncover Large-Scale Ocean Nutrient Stress

- A study published June 5 (Science Advances) combines two decades of NASA MODIS satellite data, ocean surveys, and genetic markers in Prochlorococcus to map phytoplankton nutrient stress globally. - Warming sea-surface temperatures increase stratification, reduce upwelling, and limit surface nutrients, with strongest stress in subtropical gyres and the South

Fighting Fire With Fire

- NASA’s Aqua/MODIS imagery captured smoke from numerous fires in Australia’s Northern Territory on May 28, 2026. - Many detected fires are deliberate prescribed burns, typically lit in mornings to manage savanna fuel loads. - Indigenous practices and modern programs (e.g., WALFA, Arnhem Land Fire Abatement)

NASA-Funded Study Shows Wildfire Smoke’s Hidden Ozone Toll

- A NASA-supported study found that over the past decade wildfires have increased ground-level ozone (smog) across much of the contiguous U.S., worsening air quality far from fires. - Nationally, fires offset nearly four years of ozone-control gains; in the Midwest wildfires erased about 5.3 years of progress
