    2010 Lake Superior Mooring Deployment Campaign
    (2021-03-10) Austin, Jay A; jaustin@d.umn.edu; Austin, Jay; University of Minnesota Duluth, Large Lakes Observatory
    Since 2005, investigators at UM Duluth's Large Lakes Observatory have been deploying sub-surface moorings in Lake Superior to investigate thermal structure and currents. This submission contains all temperature and current data from deployments that occurred in 2010.

    Lake Superior moored temperature and currents, Sep 2005-May 2015
    (University of Minnesota Duluth, Large Lakes Observatory, 2021-07-28) Austin, Jay A; Elmer, Cassandra; jaustin@d.umn.edu; Austin, Jay; University of Minnesota Duluth, Large Lakes Observatory
    From 2005 to the present, investigators from the Large Lakes Observatory at the University of Minnesota, Duluth have been deploying sub-surface moorings instrumented with temperature and current sensors at a variety of sites around Lake Superior. Temperature sensors at a range of depths, and profiling current meters were used to characterize the physical properties of the lake's water column. At one site, a nearly continuous time series of temperature throughout the water column exists from 2005 to the present, including winter months. Other sites are occupied for shorter spans. This archival entry covers the period 2005-2015.

    Materials to re-create "Global Dynamics of the Stationary M2 Mode-1 Internal Tide" by Kelly et al.
    (2020-11-16) Kelly, Samuel M; smkelly@d.umn.edu; Kelly, Samuel, M; University of Minnesota Duluth, Large Lakes Observatory
    In a recent manuscript, the Coupled-mode Shallow Water model (CSW) was run to examine global internal tide dynamics. This manuscript examines the sensitivity of internal-tide generation, propagation, and dissipation to model resolution, dissipation parameterizations, density stratification, surface tides, and bathymetry. This submission includes the configuration files for CSW, as well as the subset of data and Matlab scripts needed to recreate the figures and tables in the manuscript.

    Materials to re-create Coastal trapped waves: normal modes, evolution equations, and topographic generation
    (2022-03-14) Kelly, Samuel M; smkelly@d.umn.edu; Kelly, Samuel M; University of Minnesota Duluth, Large Lakes Observatory
    A recent manuscript examined coastal trapped waves (CTWs) using theory and the MIT general circulation model (MITgcm). The manuscript developed a Matlab code to generate orthogonal CTWs and then used the code to analyze MITgcm simulations of CTW generation. This submission includes the code to generate orthogonal CTWs (CTW_modes.m), the configuration and post-processing files for the MITgcm, and Matlab scripts that recreate the figures in the manuscript.

    Materials to re-create Direct Observations of Coastally-Generated Near-Inertial Waves During a Wind Event
    (2024-10-22) Kelly, Samuel; smkelly@d.umn.edu; Kelly, Samuel; University of Minnesota Duluth, Large Lakes Observatory
    A recent manuscript examined near inertial currents and internal waves in Lake Superior using shipboard observations. This submission includes the Matlab scripts and functions to analyze the observations and recreate the figures in the manuscript.

    Materials to re-create Predicting Surface Oscillations in Lake Superior from Normal Mode Dynamics
    (2024-01-16) Kelly, Samuel M; smkelly@d.umn.edu; Kelly, Samuel M; University of Minnesota Duluth, Large Lakes Observatory
    A recent manuscript examined surface oscillations in Lake Superior using observations and the MIT general circulation model (MITgcm). This submission includes the functions to analyze the observations, the configuration and post-processing files for the MITgcm, and Matlab scripts that recreate the figures in the manuscript.

    Materials to re-create results of Austin et al Zooplankton Migration paper
    (2020-11-05) Austin, Jay A; jaustin@d.umn.edu; Austin, Jay A; University of Minnesota Duluth, Large Lakes Observatory
    In a recent manuscript, zooplankton are shown to change their migratory behavior due to a change in stratification regime. This submission includes data and MATLAB scripts sufficient to recreate the four figures in the paper.

    Radiatively Driven Convection, 2019 field campaign
    (2020-10-23) Austin, Jay A; jaustin@d.umn.edu; Austin, Jay A; University of Minnesota Duluth, Large Lakes Observatory
    From May-July 2019, a large array of equipment was deployed in western Lake Superior to study a process called Radiatively Driven Convection (RDC). This occurs when solar radiation is incident on fresh water whose temperature is below the temperature of maximum density, heating and densifying surface waters, driving convection. The goal of the project was to characterize the spatial and temporal scales of this convective process.

    Shipboard turbulence and temperature profiles from the Near Inertial Coastal Experiment (NICE), 2017-2019
    (2023-01-27) Kelly, Samuel M; smkelly@d.umn.edu; Kelly, Samuel M; University of Minnesota Duluth, Large Lakes Observatory
    The Near Inertial Coastal Experiment (NICE) observed the physical properties of western Lake Superior from 2016-2020. The aim was to observe near-inertial internal waves and vertical mixing due to turbulence. Using the R/V Blue Heron as an observing platform during the summers of 2017, 2018, and 2019, a Rockland Scientific VMP-250 recorded 5,813 profiles of temperature, salinity, fluorescence, turbidity, and the turbulent kinetic energy dissipation rate, and an RBR fastDuet recorded 3,974 profiles of temperature. These profiles are archived here. Additional underway data from the R/V Blue Heron is available at the Rolling deck 2 Repository (R2R; https://www.rvdata.us/search/vessel/Blue%20Heron). Moored data from the NICE experiment was documented by Austin and Elmer (2022).
