Spring and Early Summer Temperatures in a Shallow Arctic Pond

Temperatures were recorded continuously during spring and early summer in a shallow pond on Bathurst Island in the High Arctic; thawing was rapid. After the thaw, seasonal and diel differences within the water and mud showed that frozen substrate had a marked effect on mud temperature, but that the...
