Move from a headline to the actual question, evidence, result, and uncertainty without treating every graph as a final answer.
Write the main claim in one sentence. Then label its scope: organism or process, place, depth, time period, and measured outcome. A study of surface temperature in one region does not automatically describe the deep ocean or every coastline.
NOAA National Centers for Environmental Information publishes global ocean heat-content time series. Before describing a trend, note that each product uses a stated anomaly baseline and depth layer, combines observations through an analysis method, and may be revised as data and methods are updated.
A defensible reading is: “In the selected NOAA series and depth layer, the anomaly changes over the available record.” A claim about causes requires attribution evidence; a claim about one bay or reef requires local observations.
For any plotted value, can you name its unit, depth range, baseline, spatial aggregation, interval, provider, and retrieval date? If one is missing, the graph is not ready to quote.

Ocean field notebook / paths
Move from a headline to the actual question, evidence, result, and uncertainty without treating every graph as a final answer.
Keep organism, habitat, water mass and human pressure at distinct scales, then show explicitly how the proposed mechanism links them. Relate that field focus to “Start with the claim, not the abstract” before moving to “A five-pass reading method.”
Pair a second measurement of the same process with a time series with an explicit baseline. Record depth, location, date, units and sampling effort so a change in conditions is not mistaken for a change in the ocean.
Compare “A five-pass reading method” with “Worked example: global ocean heat content.” Decide whether the pattern represents exposure, response or recovery, and state the observation period needed to tell them apart.
