A marine biologist investigated the relationship between seawater temperature and the metabolic rate of a specific species of shore crab (Carcinus maenas).
The seawater temperature was measured in degrees Celsius (∘C^{\circ}\text{C}∘C) using a digital probe. The metabolic rate was measured by recording the rate of oxygen consumption in microlitres of oxygen per gram of body mass per hour (μl O2 g−1 h−1\mu\text{l O}_2\text{ g}^{-1}\text{ h}^{-1}μl O2 g−1 h−1) over a continuous 2-hour period in a respiration chamber.
