Abstract:

From 2015 to 2022, mid-summer vertical profiles of temperature, chlorophyll a fluorescence, turbidity, and fDOM were collected in a set of 17 lakes in Banff and Yoho National Parks, Canada. These lakes are located across montane, sub-alpine and alpine ecoregions and they vary widely in elevation (1300-2423 m a.s.l.), surface area (1.5-116 ha) and maximum depth (2.4-39.2 m). Eight of the lakes receive surface and/or groundwater hydrologic inputs from glaciers within the catchment, and the other nine lakes are not glacially-fed. Vertical profiles were collected in each lake within one or two days of an index sampling date between late July and early August using an Exo2 vertical profiling sonde. Measurements were taken at 1 s intervals as the sonde was lowered slowly through the water column, and then averaged over 0.5 m depth intervals. In addition, attenuation rates were estimated for 305 nm, 320 nm, and 380 nm, and PAR (400-700 nm) as the slopes of log-linear regressions of irradiance vs. depth. Downwelling irradiance measured with a Biospherical Instruments underwater radiometer.

Vertical Profile Data are contained in Can_Rocky_Mtn_Lakes_Profiles.csv. Attenuation rates are contained in Can_Rocky_Mtn_Lakes_Kd.csv. Information about study lakes is contained in Can_Rocky_Mtn_Lakes_Site_Information.csv.

Methods and protocols used in the collection of this data package

Description:

Vertical profiles were collected using a YSI Exo2 multiparameter sonde at or near the deepest part of the lake. The sonde was lowered by hand through the entire water column at a rate of approximately 30 seconds/m. At 1 second intervals, measurements were taken for temperature (°C) chlorophyll a fluorescence (in RFU, relative fluorescence units), turbidity (FNU), and fluorescing dissolved organic matter (fDOM in RFU). Data were only collected as the sonde was lowered. Measurements were averaged for 0.5 m intervals.

Instrument(s):

YSI Exo2 Sonde

Description:

Water transparency was quantified using a cosine-corrected

submersible radiometer. While being lowered slowly through the water column

from the surface to the bottom or a depth of 20 m, this instrument

simultaneously measured depth and downwelling irradiance of

three UVR wavelengths (305, 320, and 380 nm, measured as midpoint

of 8–10 nm wide bands encompassing >50% peak response

within the band), as well as PAR (400–700 nm) at approximately

0.25 s intervals. Diffuse attenuation coefficients (Kd) were estimated

for each wavelength as the slope of the log-linear portion of

the irradiance versus depth relationship.

Instrument(s):

Biospherical Instruments BIC multichannel profiling radiometer
