Identify the exact claim
A news article may combine a study’s finding with background, expert interpretation, and a headline written for a broad audience. Begin by isolating the specific claim you want to check. Is it about a measured change, a proposed explanation, a newly documented organism, or a forecast? Each type requires a different kind of source and evidence.
Record the article’s wording and look for links, author names, a journal, a report, or a dataset. A phrase such as “researchers found” may lead to a primary paper, but it may also refer to an institutional summary. Follow the link to the most direct source available. If no link appears, search the title, authors, or distinctive technical terms rather than relying on a copied headline.
Open the underlying source
When you locate a paper, check that it matches the article’s subject, date, and research group. Read the abstract, then inspect the methods, results, and relevant figures. For a dataset or monitoring result, find the data description and its time and place coverage. Confirm the source actually reports the claim rather than simply discussing the same topic.
Compare the public summary’s nouns and verbs with the source. “Researchers observed a rise at several stations” is narrower than “the coast is experiencing a rise.” “May be linked to” differs from “caused by.” Also check whether the news article describes a model scenario as a forecast or whether it reports a direct observation. Small wording shifts can change the meaning substantially.
Check context and limits
Look for sample size, location, period, and method. These details show how far the claim can travel. If a study sampled one habitat during a limited window, the result may not establish a coastwide pattern. If a paper reports a proposed mechanism, check whether its methods tested that mechanism or whether the discussion presents it as a possible explanation.
Read the study’s limitations and any uncertainty language. A news story may omit them for brevity, even when they are essential to interpretation. Record what the source directly supports, what the authors infer, and what the article adds. If a claim depends on an earlier study, follow that citation as well; sometimes the most relevant evidence sits one step farther back in the chain.
Write a source-aware summary
A useful note has two versions of the claim: the public article’s wording and a careful wording based on the source. For example: “Article says the species is expanding; cited paper documents records at two additional sites and discusses expansion as a possibility.” This makes the difference visible without assuming the article was deliberately misleading.
Following a claim to its source turns reading into verification. Check that the cited work addresses the same organism or variable, and preserve its setting, evidence type, and qualifications. If you cannot locate the underlying support, mark the claim as unverified rather than treating repetition as confirmation. That habit produces a more accurate account of marine research.
