Ichthyologist Coloring Page - Tools of the Trade
This illustration is for an Ichthyologist coloring page. This coloring page can easily be added to lesson plans for students in science classes.
On this coloring page, title "Tools of the Trade", it shows two scientists (one male, one female) wading in shin-high water. The male scientist is holding a net and the female scientist
...I Am A(n)...Ichthyologist
Welcome to the "The I Am A..." series. This is the fifth video in a series of USGS whiteboard animations that highlight USGS careers. The concept is to show "what society (or my mom) thinks I do" compared with "what I really do." One image captures a more whimsical representation of a "scientist" and the second demonstrates a more accurate representation of what we really
USGS Pacific Seabird Research
Alaska's coastal and offshore waters provide foraging habitat for an estimated 100 million birds comprising more than 90 different species. Researchers at the USGS Alaska Science Center work in collaboration with many partner agencies, non-governmental organizations, universities and rehabilitation centers to investigate seabirds. USGS ecosystems research is focused on
