Roberta Hamme

Roberta Hamme is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Roberta Hamme rather than just read about it. In short: Roberta C. Hamme is a Canadian chemical oceanographer at the University of Victoria.

Key takeaways

Roberta Hamme belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Roberta Hamme to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Roberta Hamme from memory before moving on to harder problems.

Reference excerpt

Roberta C. Hamme is a Canadian chemical oceanographer at the University of Victoria. She holds a Canada Research Chair in Ocean Carbon Dynamics (Tier 2).

Education, research and career She did her Phd and MSc at University of Washington and BA at Pomona College. Previously, Hamme's research demonstrated that the 2008 eruption of the Kasatochi island volcano resulted in one of the largest phyotoplankton blooms observed in the subarctic North Pacific, covering between 1.5 and 2 million square kilometres of ocean. Hamme also noted that this phytoplankton bloom had a minor impact on carbon dioxide absorption levels as it absorbed only 0.01 petagrams of carbon. Researchers later linked this bloom to an increase in the sockeye salmon population in British Columbia. Hamme is now an associate professor in the School of Earth and Ocean Science at the University of Victoria, where her lab studies air-sea exchange. She is leading a team of Canadian researchers who have received $540,000 in funding from the Advancing Climate Change Science in Canada initiative to investigate the role of the ocean in slowing down the effects of climate change, including measuring carbon dioxide absorption levels and predicting future changes in Canadian oceans. Hamme's research has been cited over 1,000 times, and has an h-index and i10-index of 16 and 23 respectively. She was appointed as a Canada Research Chair in Ocean Carbon Dynamics (Tier 2) in 2014, which was renewed in 2019.

Worked examples

Example 1 — a first encounter with Roberta Hamme

Start with the simplest possible case. Write down what Roberta Hamme claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Roberta Hamme before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Roberta Hamme ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Roberta Hamme

In research: Roberta Hamme appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Roberta Hamme in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Roberta Hamme is common in secondary-school and first-year university syllabi. It links to neighbouring topics Academic staff of the University of Victoria, Canadian oceanographers, Canadian women scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Roberta Hamme outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
