For This Project
Diving physiology in penguins has been extensively studied within the larger, deep diving species reminiscent of emperor and gentoo penguins, nonetheless the blood oxygen storage capability of the mid-depth diving crested penguins is much less understood. For this mission, I measured the concentrations of hemoglobin and hematocrit in three species of crested penguins (Fiordland penguin/tawaki, erect-crested penguin, and Eastern rockhopper penguin) in New Zealand to match oxygen storage capability and dive depth/time. Data evaluation for this venture is still underway, however preliminary results recommend that the larger erect-crested penguin has the best hemoglobin and hematocrit values of the three suggesting a higher oxygen storage capacity in the blood and extra environment friendly transport of oxygen to the tissues allowing deeper or longer dives. Data from this undertaking was cited in New Zealand Geographic 2023 article The long run is Written in Penguin Blood (see Media tab for hyperlinks). Publication of a short notice containing these values is on deck for Notornis.
The Apple Watch Series 6 feels prefer it has perfected many of the features I appreciated about its predecessor. It has a brighter all the time-on show, a more highly effective processor, faster charging and two new colorful choices to choose from. But the function I was most excited to try out was its new sensor that measures oxygen saturation in the blood (aka SpO2) with the tap of a display screen.
