Spatial and Temporal Variability of In-Stream Functioning within a Forested, Headwater Piedmont Watershed
… reach. Within this setting, three temporal "hot-moments" of in-stream nutrient processing were observed: the release of ammonium and phosphate during the warm - but shaded - growing season; nitrate uptake during autumnal leaf-fall; and a unique spike of nitrate uptake and respiration-induced …

Adaptive sampling for multiscale environmental sensor networks
… this research expands the definition of a “hot moment”, a term previously used to describe times of high biogeochemical activity, to include periods of elevated signal complexity, which is when dense data collection is most needed. Under this new definition, an indicator for hot moment …

HYPORHEIC FLOW, RESIDENCE TIMES AND NITROGEN REACTIONS IN A RIFFLE-POOL SEQUENCE, TRUCKEE RIVER, NV.
… days, respectively. The riverbed has distinct hot spots and hot moments of high biogeochemical activity in both the riffle and pool areas. Nitrate and dissolved oxygen were greater in the riffle transects as compared to pool transects, due to mixing among short and long flow paths. …

Identifying control points of excessive nitrate load in a pastoral catchment to support lake management
… This study aimed to determine where and when hot spots and hot moments can be characterised as control points for freshwater contaminant losses in the pastoral catchment. Multi-isotope analysis, high-frequency data collection, and modelling were utilised in identifying and describing potential …
