Title:Ultraviolet-visible spectroscopy absorbances for dissolved organic matter from Lake Mendota from June – November 2017
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Dissolved organic matter (DOM) is a complex mixture of organic compounds found in all natural waters. Its composition affects its reactivity towards numerous processes. Its composition is a function of both its source (e.g., allochthonous or autochthonous) as well as the extent of environmental processing it has undergone (e.g., chemical or biological degradation). Ultraviolet-visible (UV-vis) spectroscopy is an analytical technique commonly used to assess the composition of dissolved organic matter in water samples. Here, we present spectra from Lake Mendota samples collected from June - November in 2017 at the surface of Lake Mendota as well as at specific depths within the water column. All samples were collected near the NTL-LTER research buoy. Absorbance values are listed for wavelengths 200 - 800 nm for each sample.

Methods and protocols used in the collection of this data package
Description:

Samples were collected either as an integrated surface samples or depth-discrete samples. For the integrated surface samples, a flexible piece of tubing 12 m in length was lowered into the lake and corked with a rubber stopper. The resulting water inside was a composite of the top 12 m of the lake and was emptied into a sampling bottle. For the depth-discrete sample, a rope labelled with depth measurements was lowered into the lake to a desired depth, and then a peristaltic pump was used to pump water from that depth up and into a sampling bottle. In either case, samples were immediately brought back to the laboratory and filtered through 0.45 µm filters (MDI, nylon) within 24 hours and stored in the dark at 4°C. A Shimadzu 2401PC Recording Spectrophotometer was baselined with ultrahigh purity water (18.2 ΜΩ, Milli-Q). Samples were put into quartz cuvettes and absorbances were recorded from 200 – 800 nm with Milli-Q as the reference.
