Limnocline: Lake Profiles is an offline limnology workbench for depth profiles, thermocline screening, oxygen structure, and repeatable lake-station comparisons. KEY FEATURES - Depth-profile plotting - Temperature and dissolved-oxygen records - Strongest sampled temperature-gradient cue - Conductivity and field-note context - Editable profile plus CSV import - Basin and sampling-session comparison - Calibration and sensor-lag references - Local PDF analysis packet - Forty original offline limnology reference plates ONE-TIME AND PRIVATE - One paid download; no subscription or in-app purchase - No account, advertising, analytics, tracking, or developer-operated backend - Core tools and bundled reference material work offline - Work remains on device unless you deliberately import, share, or export through an Apple system interface Field interpretations depend on calibrated instruments and local protocols.
