Deforestation in Bolivia

Samenvatting:
This visualization adapted from NASA features two satellite images from 1984 and 2000 that show the dramatic deforestation of the Bolivian rainforest.

Controlling Water Run-off

Samenvatting:
This video shows how the environmentally friendly design of the Visitor Center at Bernheim Arboretum and Research Forest near Louisville, Kentucky helps to control non-point-source water pollution, conserve water, and prevent erosion by slowing down and collecting water run-off.

Greenland Ice Sheet Project 2: A Record of Climate Change

Samenvatting:
Using images and graphs, this interactive resource illustrates scientists' efforts to study Earth's climatic history for the last 250,000 years by drilling into the Greenland Ice Sheet and examining ice cores.

Water Solutions: Stream Restoration

Samenvatting:
This video explores how Bernheim Arboretum and Research Forest near Louisville, Kentucky restored a channelized stream to its original meandering path.

Mountain of Ice: If the Ice Melts

Samenvatting:
This interactive resource adapted from NOVA Online features a collection of images that show what would happen to selected coastlines around the world if the Antarctic Ice Sheet melted.

High Sulfur Coal and Acidic Water

Samenvatting:
In this video, after briefly discussing the geologic era in which Kentucky’s high-sulfur coal formed, a geologist demonstrates how high-sulfur coal causes acid mine drainage.

Documenting Glacial Change

Samenvatting:
This collection of comparative glacier images adapted from the National Snow and Ice Data Center shows substantial changes in five Alaskan glacier positions over periods of 60 to 100 years.

Recycling and Restoration

Samenvatting:
This video explains how Bernheim Arboretum and Research Forest near Louisville, Kentucky used recycled cypress from pickle vats to build its visitor center and then “paid back” nature by creating a cypress-tupelo swamp.

Arctic Sea Ice Satellite Observations

Samenvatting:
In this interactive activity produced for Teachers' Domain, learn how Arctic sea ice has changed over the past 25 years in terms of maximum winter extent, concentration, and the timing of breakup each spring.

Results of Mine Drainage Remediation

Samenvatting:
In this video, a biologist visits Lower Rock Creek in Pulaski County, Kentucky to show how acid mine drainage remediation has increased the stream’s pH from acidic levels almost to 7, which is neutral. Many fish species such as minnows, trout, and bass have returned to Rock Creek.
