Timed oceanographic data reading
Interpret a source-labeled oceanographic record under agreed assessment conditions: profiles, counts with sampled volumes, life-stage survival, defined-area communities or catch with effort. Public observations and supplied synthetic data must keep their provenance labels. Publish the target, allowed references, timing and approved accommodations before assessment; scientific reasoning, not speed or confidence, determines the evidence.
Prepare with profiles, plankton and oxygen rates, recruitment, community sampling and CPUE and carbonate chemistry. Use a fresh changed-value case for assessment. Data interpretation is not a field/practical credential and does not certify an unobserved practical skill.
| Criterion | Developing | Proficient | Mastery |
|---|---|---|---|
| Reading graphs & tables | Misreads axes or columns and cannot tell which line or column is which. | Reads a simple graph but confuses axes on a two-variable plot or misaligns a tide-table row. | Reads temperature–salinity–depth profiles, tide tables, and distribution maps accurately, tracking the right line, column, and axis every time. |
| Extracting values and denominators | Omits units, source or sampled amount. | Reads values but loses a volume, area, time or stage denominator. | Extracts values with temperature, salinity scale, oxygen and uncertainty; correctly applies volume, area, time, effort or life-stage denominators. |
| Interpreting patterns | Sees a wiggly line but cannot name the pattern behind it. | Spots an obvious feature but mislabels it — calls a tidal cycle a trend, or misses the thermocline. | Names the pattern from the data — the thermocline in a depth profile, the tidal cycle in a tide table, a plankton bloom, an oxygen minimum zone. |
| Drawing a defensible conclusion | States an unsupported causal or population claim. | Cites values but omits uncertainty or alternatives. | Defends a bounded conclusion with specific values; distinguishes stock from catch, settlement from recruitment and community from producer respiration where relevant. |
| Accuracy and checking | Cannot yet identify a unit or arithmetic inconsistency. | Checks with prompts but misses a changed assumption. | Checks units, denominators, calculations and a fresh transfer under the agreed timing, references and accommodations; speaking speed is not graded. |
Integration is reported separately and cannot lower the science grade or block a science demonstration pass. Science and practical criteria determine that pass. Before assessment, publish the target list, task, permitted references, timing, and accommodations. Assess scientific reasoning and safe technique, not confidence or speaking speed.
“Temperature holds near 22°C down to about 40 metres, then drops sharply to 8°C by 100 — that steep band is the thermocline. Below it the water’s cold and dense, so the two layers barely mix. I read those depths straight off the profile before I called it.”
“The line goes down, so it’s getting… colder deeper? I’m not sure what to call that part. I’d need more time to figure out the units.”
Use supervised explanation, the learner's own calculations and a changed case to check understanding. Practice answers are public; do not present them as a secure exam. Follow the approved AI-use contract and accessible response format. Only observed, separately approved practical work can establish tool proficiency; integration remains separately reported.
