Title:Hourly time series of Ives Lake (Huron Mountains, Marquette County, MI) Water Temperature-Depth Profiles, 2013-2022 (continuing study)
Alternate Identifier:DOI PLACE HOLDER
Abstract:

Long-term measurements of lake temperatures are essential to providing insights into local and regional changes in climate since large, still water bodies effectively act as a high-frequency filter. Ives Lake is a 30.7 m deep water body in northern Marquette County, in Michigan's Upper Peninsula. Beginning in 2013, temperature readings have been collected hourly from a string of twelve sensors located near the deepest point of the lake (approximately 46.84874 N lat, 87.84895 W long; identified by sonar survey in 2010 by first author). Measurements are continuing. The purpose of the project is to collect a data record of sufficient duration to determine if water temperatures are warming, and if the dates of autumn lake turnover are shifting toward later in the year.

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

Twelve sensors were attached to a nylon rope with a cement block at one end and a float at the other. Vertical spacing between sensors was uneven; shorter spacing near the surface allowed better vertical resolution in the upper part of the water column where temperature change was most rapid. Depths from surface downward are: 0, 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, and 30.7 m (note that data records are by height above lake bottom -- the inverse of this series).

Sensors were replaced over time. Sensors at -0.7/30.0 m (depth from surface/height above lake bed), -3.7/27.0 m, -9.7/21.0 m, -15.7/15.0 m, -21.7/9.0 m, and -27.7/3.0 m were replaced 12 June 2013. All other sensors were replaced 1 Sept 2019.

The instrument string was removed from the lake each year for service and data downloading, typically in August, and then returned to the same location.

There is some missing data due to sensor malfunction or power loss, and during short intervals between sensor removal and redeployment during spring service and reading. In addition, in some years, ice rafting during spring breakup resulted in movement of the sensor string. The sensor string was returned to the original position within a few weeks of the ice-rafting event, and the impacted portion of the data record was deleted.

The data are made available “as is.” This file will be replaced annually as new data is collected and appended to the record.

Instrument(s):The sensor used are Onset Corporation HOBO Water Temperature Pro V2 (U22-001), which have an accuracy of +/-0.21°C from 0 to 50°C, and a resolution of 0.02°C at 25°C.

Abstract:

The mesoscale network of climate-observation stations in the Huron Mountain Club has been in operation for nearly 20 years. It has expanded gradually to its present configuration of 36 temperature-monitoring installations, four weather stations, and a water column temperature monitoring array of sensors in Ives Lake.
