Data Archives

A core objective of HMWF’s research program is promotion of long-term and integrative research by preserving and making generally available data-sets generated by HMWF-sponsored projects.  Many of these data-sets establish valuable baselines for comparative studies involving the relative pristine ‘reference ecosystems’ of the Huron Mountains. 

We are working to make old and new data-sets available through searchable public archives. We encourage potential users of these data-sets to recognize the interests of original data-collectors and to collaborate fully and appropriately in incorporation into further studies and analyses.  

This page lists some data-sets that are available either in public archives or by request to the Director of Research.  Many other data-sets may eventually become available. If you have interests in data behind any of the reports and papers listed elsewhere at our site, contact the Director of Research or original researchers to explore possibilities.

DATA AVAILABLE IN PUBLIC ARCHIVES: Data-sets listed here are accessible in public archives and repositories as described

  • Population studies — monitoring and genetics: Many studies have documented population status for a wide range of taxa, some with associated genetic studies. We are only beginning to compile these in accessible archives:
    • Myers, P, A. Poor, R. Manville. Long-Term Studies of Huron Mountain Club Small Mammal Populations  ver 1. Environmental Data Initiative.
  • Dendrochronological data-sets: Multiple studies at the Huron Mts have made use of tree-ring measurements from both living and dead trees for climate reconstruction and analysis of fire history as well as address of population and community ecology questions. The following data are currently available from archives as noted; additional data-sets exist and can be provided on request.
    • Dye, A. 2018. Tree Rings, Huron Mountain Club ver 0. Environmental Data Initiative. [Annual growth sequences for ca. 170 cores, mostly Acer saccharum and Tsuga canadensis, associated with several permanent plots in Woods data-set listed above. Used in Dye PhD Thesis and associated papers.]

  • Palynological/paleoecological data: Counts of pollen assemblages from lake sediment cores along with age/depth relationships and some other data, from several studies, are deposited in the “Neotoma Paleoecology Database”, accessible via the Neotoma Explorer. Data-sets from the Huron Mountains include:
    – Two cores from Lake Ann (Neotoma site 24091) from the work of Steve Jackson and Jennifer Andersen, with charcoal, macrofossils, and chronologies as well as pollen (ref. Andersen’s 2005 M.S. Thesis), and surface pollen assemblage from work of Linda Brubaker in 1970s.
    – One core by Jackson and Andersen from Trout Lake (Neotoma site 24108), and surface pollen from Brubaker,
    – Pollen counts from a complete core from Canyon Lake (Neotoma site 2956) by Margaret Davis and colleagues (ref. Davis, Schwartz, and Woods 1991 on publications page).
    Other paleoecological data-sets may be available (ref. Anderson-Carpenter et al. 2011 on publications page).


* General GIS coverages: We can provide basic GIS coverages on request for HMWF researchers.  These include hydrological features, trail/road systems, maps of habitat classifications and forest types, and the boundaries of Huron Mt. Club holdings

* Microclimatological data (Nelson and Hinkel): Fifteen years (2004-present) of temperature and some additional microclimatological measurements from a network of ca. 30 monitoring stations across Huron Mt. Club lands (Hinkel and Nelson 2012: DOI 10.1007/s00704-012-0585-2).  Data from this network can be made available to other researchers.

* Lake Bathymetry: From intensive sonar surveys conducted in 2010-2011 by Kenneth Bockheim, Fritz Nelson, and Ken Hinkel for all Huron Mt. Club interior lakes. Bathymetric maps available here (Part 1, Part 2); higher resolution images of maps, shapefiles with sonar transects, and raw sonar data are all available for individual lakes.

* Seismic and Core Data for Inland Lake Sediments: Andrew Breckinridge (University of Wisconsin – Superior) conducted seismic reflection (CHIRP) surveys of lake sediments of Ives, Conway, and Pine Lakes, and collected sediment cores from (First) Pine and Conway. The study attempted to use seismic profiles and sediment stratigraphy to constrain early Lake Superior levels in these lakes that are thought to have originated as Lake Superior embayments. Raw seismic data and data from optical scans of cores are available, along with a summary report with images of seismic transects.

* Temperatures from Ground-water Monitoring Wells in Salmon Trout River: In connection with studies of ‘coaster’ brook trout spawning behavior, Matt Van Grinsven and Dr. Alex Mayer (Michigan Technological Univ.) established monitoring wells in the bed of the Salmon Trout River and monitored temperature profiles over depth below streambed. Data for the 2008 season are available.

* Bird communities in jack pine forests: Bird community data collected by Dr. Gregory Corace. Data include point counts and associated forest composition data, 2014-2017, for 45 sample points in jack pine forests. Bird counts for two dates each year. Most plots were in areas with varying intensity of jack pine removal in 2015-16; a handful remained unmanaged.

* General Land Office witness-tree data: All survey data from original surveys of Marquette Co. ca. 1850s.

*Small mammal community data: Small-mammal capture data from 14 sampling grids trapped repeatedly, 2004 and 2005. M.S. Thesis research by Allison Poor, under direction of Dr. Phil Myers (University of Michigan), reported in Myers et al. 2009 ( ). Sampling replicated earlier work (1949) by Richard Manville.

* Historical and recent bird community surveys: Two studies documented breeding bird communities by quantitative surveys along identical transects ca. 1990 (Kielb et al.) and ca. 2020 (Buron et al.)
