able to not only track distances, but also qualitatively measure the tilt and velocity of the animal. This information has many implications for research, and has been important towards studies that investigate how these animals’ physiology changes throughout the duration of a long swim. For example, one study showed that white sharks maintain energy for long distance journeys by using up their lipid reserves in their livers, thereby changing the tilt at which they swim, which can be detected by the electronic tags. In addition, Block has embarked on several projects to track large populations of oceanic predators, resulting in new discoveries of certain population congregations in different locations such as the
Caribbean Sea.
226:, for much of her career. She has done extensive work to improve the quality and scale of tagging operations in order to better analyze large scale movements of these species throughout different oceans. She has specifically contributed to two different new kinds of electronic tags, and has utilized professional relationships with commercial and recreational fishermen to facilitate more efficient tagging processes.

conducted in controlled environments like in the Tuna
Research and Conservation Center, where Block and her team can make specific measurements and observations of bluefin tuna and other large oceanic species. Some of the findings through this research have been in identifying the genes responsible for temperature regulation, and the gene expression controlling those genes.
33:. She has published numerous bodies of work throughout her career in marine biology and chemistry, mainly focusing on the biology and chemistry of metabolism in different tuna and shark species. Additionally, she has helped develop two new types of electronic tags for large pelagic predators in order to track the migrations of large oceanic predator species.

Block's research has added significant contributions to the study of migration and population in oceanic ecosystems. This field is particularly hard to study because of the challenges of effective and ethical tagging of marine species. With new types of electronic tags, Block and her team have been

Stanford faculty in 1994. Since then, she has spent multiple decades researching oceanic predators and teaching classes, specifically for the Stanford at Sea program. She has also established and lead the Tuna Research and Conservation Center, which is a unique center that focuses on

Block has published and helped conduct multiple research studies about the effect of temperature changes on physiology of a variety of species. Temperature can have varying effects on organisms, and is especially hard to study for large oceanic species in the wild, so much of the research must be

Block's three main types of contributions to research in her field are in tracking large-scale migrations and populations of ocean predators, researching temperature's effect on physiology of large pelagic predators, and investigating the effect of movement on the metabolism of these large ocean

To study metabolism in the wild, Block and researchers have been able to use specific types of tags with speed- and temperature-measuring capabilities, where they can make a correlation between the speed of the animal with the amount of oxygen entering through the gills. They can compare this
