    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.

    Lake Superior moored temperature and currents, Spring 2015 to Spring 2021
    (2022-04-15) Elmer, Cassandra; Austin, Jay A; jaustin@d.umn.edu; Austin, Jay A; University of Minnesota, Duluth Large Lakes Observatory
    This document describes the data archive for 2015-2020 Lake Superior moorings. Data types include temperature, velocity, and acoustic backscatter. Temperature data comes from thermistors and 𝜒pods while velocity and acoustic backscatter intensity data comes from Acoustic Doppler Current Profilers (ADCPs). Covered in this dataset are 46 mooring deployments, 514 thermistor records, 10 𝜒pod records, and 26 ADCP records. This archival entry covers moorings deployed in 2015 through 2020; data from 2020 deployments extends into 2021. See also the previous archival entry for 2005-2014 deployments (Austin and Elmer 2021) and archival entries for the Radiatively Driven Convection (RDC) deployments of 2019 (Austin 2020) and 2021 (Elmer and Austin in progress).

    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.
