This dataset includes pollen sample weight in grams and percent crude protein collected by honey bees (Apis mellifera) across 38 apiaries in Minnesota, North Dakota, and South Dakota approximately weekly from June through September in 2015 and 2016. Additionally it includes the hectares of different land covers (corn, Zea mays, & soybeans, Glycine max, grasslands, bee forage crops, and wetlands) located within a 4 km radius of each apiary.

This data release includes the airborne magnetic survey data collected from the Manchester region of Iowa. The Mineral Resources Program of the U.S. Geological Survey is tasked with understanding the nation's mineral resources. Precambrian rocks concealed under Paleozoic sedimentary rocks in northeast Iowa are poorly mapped and understood. Detailed high-resolution airborne magnetic surveys, ground gravity surveys, and limited borehole data are being used to better understand the lithology and structure of concealed Precambrian rocks. The primary goal of the airborne magnetic survey is to map lateral variations of magnetization that are related to differences in rock type.
