Abstract. Empirical evidence demonstrates that lakes and reservoirs are warming across the globe. Consequently, there is an increased need to project future changes in lake thermal structure resulting biogeochemistry order plan for likely impacts. Previous studies of impacts climate change on have often relied a single model forced with limited scenario-driven projections relatively small number lakes. As result, our understanding effects fragmentary, based scattered using different data...
A Global Lake Ecological Observatory Network (GLEON; www.gleon.org) has formed to provide a coordinated response the need for scientific understanding of lake processes, utilising technological advances available from autonomous sensors. The organisation embraces grassroots approach engage researchers varying disciplines, sites spanning geographic and ecological gradients, novel sensor cyberinfrastructure synthesise high-frequency data at scales ranging local global. platform rigorously...
AbstractAbstractAnthropogenic activity has greatly enhanced the inputs of nitrogen (N) and phosphorus (P) to lakes, causing widespread eutrophication. Algal or cyanobacterial blooms are among most severe consequences eutrophication, impacting aquatic food webs humans that rely on lakes for ecosystem services. In New Zealand, recent debate relative importance N versus P control limiting occurrences algal centered iconic Lake Rotorua (North Island). Water quality in declined since late 1800s...
Abstract Transparency is a fundamental characteristic of aquatic ecosystems and highly responsive to changes in climate land use. The transparency glacially‐fed lakes may be particularly sensitive sentinel these changes. However, little known about the relative contributions glacial flour versus other factors affecting light attenuation lakes. We sampled 18 Chile, New Zealand, U.S. Canadian Rocky Mountains characterize how dissolved absorption, algal biomass (approximated by chlorophyll ),...
The use of high-frequency sensors on profiling buoys to investigate physical, chemical, and biological processes in lakes is increasing rapidly. Profiling with automated winches that collect chlorophyll fluorescence (ChlF) profiles 11 the Global Lake Ecological Observatory Network (GLEON) allowed study vertical temporal distribution ChlF, including formation subsurface maxima (SSCM). effectiveness 3 methods for sampling phytoplankton distributions lakes, (1) manual profiles, (2) single-depth...

Abstract. Automated calibration of complex deterministic water quality models with a large number biogeochemical parameters can reduce time-consuming iterative simulations involving empirical judgements model fit. We undertook autocalibration the one-dimensional hydrodynamic-ecological lake DYRESM-CAEDYM, using Monte Carlo sampling (MCS) method, in order to test applicability this procedure for shallow, polymictic Lake Rotorua (New Zealand). The involved independently minimizing...
Abstract Phytoplankton biomass and production regulates key aspects of freshwater ecosystems yet its variability subsequent predictability is poorly understood. We estimated within‐lake variation in using high‐frequency chlorophyll fluorescence data from 18 globally distributed lakes. tested how at monthly, daily, hourly scales was related to wind, water temperature, radiation within lakes as well productivity physical attributes among Within lakes, monthly dominated, but combined daily were...
ABSTRACT: Associations between the El Nino Southern Oscillation (ENSO) climate pattern and temporal variability in flow 12 water quality variables were assessed at 77 river sites throughout New Zealand over a 13‐year period (1989 through 2001). Trends determined for same period. All 13 showed statistically significant linear regression relationships with values of Index (SOI). The strongest temperature (mean R 2 = 0.20), dissolved reactive phosphorus (0.18), oxidized nitrogen (0.17)....
Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater vertical gradients, many lakes around world. Though studies highlight warming of water temperatures worldwide, less is known about trends full structure which been changing consistently both direction magnitude. Here, we present a globally-expansive data set summertime in-situ temperature profiles from 153 lakes, with one time series beginning as...
