Glacial meltwater drives high CH4 supersaturation in Maxwell Bay, King George Island (Southern Ocean)

Limnology and Oceanography Letters, EarlyView.
Abstract Coastal waters exhibit the highest and most dynamic dissolved CH4 concentrations in marine environments, but significant knowledge gaps on the distribution and emissions, particularly in the Southern Ocean, still exist. We quantified dissolved CH4 concentrations and sea–air fluxes in the coastal waters of Maxwell Bay, King George Island ...

Extending monitoring with sediment archive approaches: Comparison of biomonitoring, metabarcoding, and biomarkers to assess past phytoplankton dynamics

Limnology and Oceanography: Methods, EarlyView.
Abstract Sedimentary archives can provide valuable insights into the study of anthropogenic impacts on marine and limnic ecosystems over centennial and millennial timescales, potentially extending the temporal breadth of observation‐based biomonitoring.

Distribution and diversity of exotic plant species in montane to alpine areas of Kosciuszko National Park [PDF]

, 2013
Diversity and distribution of exotic plant taxa in Kosciuszko National Park in south-eastern Australia were reviewed based on 1103 records of exotics from 18 vegetation surveys conducted between 1986 and 2004.

A correction model for quenching effects on chlorophyll a fluorescence measurements in lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Characterizing the vertical structure of phytoplankton biomass is key to understanding the light, nutrient, and mixing dynamics driving lake ecosystems. In situ fluorometry is widely used in limnology to obtain chlorophyll a (Chl a) measurements as proxies for phytoplankton biomass.

Flying towards the Future: Using Drones to Detect Lizards in Remote Alpine Terrain

Drones
Climate change is exerting significant impacts on ecosystems worldwide, with alpine regions being particularly vulnerable. Alpine fauna is relatively poorly understood, particularly in terrain which is difficult for humans to survey.

Identifying conditions associated with outliers produced by three different chlorophyll fluorometers: A comparison of instrumentation and development of correction formulae

Limnology and Oceanography: Methods, EarlyView.
Abstract Measurements of chlorophyll concentration reported by fluorometers (fChl) are used in environmental research and monitoring, as inputs to models, and in the interpretation of remote sensing data. Researchers and managers benefit from understanding how to interpret and ensure the accuracy of fChl data collected by in situ fluorometers. Although
