Data Archives

HMWF urges researchers to make original data freely available to other researchers either through existing on-line archives, by depositing data-sets with the Foundation, or by making data-sets available on request.  This page lists some of the data-sets available through the Foundation or public archives.  Researchers interested in using these data may follow the links provided, or contact the Director of Research (see ‘contact us’ page) for other data-sets. 

Use of some data-sets may be restricted by agreement with original researchers. In all cases use of these data-sets in new analyses and publications must appropriately acknowledge original providers of data as stipulated by those providers.  This may call for co-authorship of resulting publications.

For information about data-sets from projects not listed here, contact the Director of Research or use publications to contact researchers directly.


* 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.

* Forest compositional data (Stuart, Barnes et al.): Over 400 plots (450 m2), established in 1987-88, by Thomas Simpson, Philip Stuart and collaborators from the Burton Barnes lab (Univ. Michigan), cover a large portion of the old-growth ‘Reserved Area’ of Huron Mt. Club lands. Data include plot coordinates, stem measurements of tree stratum, subsamples of ground vegetation, soil properties, and topography. This work is summarized in HMWF’s “Occasional Paper #4”.

* 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.


  • Biogeochemical and wather chemistry data for Canyon Lake: Two data-sets from work by Swanner, Lambrecht, Wittkop, and others (associated with several publications/theses) are held at Environmental Data Initiative, accessible and citable at:
    • Lambrecht, N., S. Katsev, C. Wittkop, S. J. Hall, C. Sheik, A. Picard, M. Fakhraee, and E. D. Swanner. 2019. Biogeochemical and physical controls on methane fluxes from two ferruginous meromictic lakes. doi:10.6073/pasta/58e69641730756555069631ebc687a61
    • Swanner, E. D., N. Lambrecht, C. Wittkop, S. Katsev, G. Ledesma, and T. Leung. 2021. Water properties of Brownie Lake, MN and Canyon Lake, MI from 2015-2019. doi:10.6073/PASTA/4EAF698B4EFBAF793B83D95F464D1672
  • 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).
