Abstract
Czech plant physiologists have been studying within- and inter-seasonal variability of water temperature and DOC in several small terrestrial lakes at James Ross Island, Antarctica.For the study, two lakes rich in microbiological mats were chosen. Lake Dulanek is located nearby Windy Pass at the height of 220 m a.s.l. It is a small lake of area of about 25 m2 formed in a shallow depression at a SE-facing foothill of the Lachman Crags mesa The depth of water column varies within a season. It is about 1.1 m at the beginning of austral summer and 0.7 at the end of austral summer. Interlago Lake is located in between Big and Small Lachman Lakes. It is a shallow small area located in sedimentary rocks and surrounded by rich moss and lichen vegetation formed in the neighbouring seepages on west side. It is located at 10 m a.s.l. and 100 m distant from sea cost. In February 2014, thermocouples, PAR sensors and oxygen electrodes (WTW) were installed into a depth of 40 cm in each lake and linked to a datalogger (EdgeBox, Environmental Monitoring Systems, CZ). At each site, data were measured and stored in 5 min interval, so that daily fluctuations in environmental characteristics and DOC could be monitored.
