In the summer of 2013, C-MORE conducted a series of experiments to observe and interpret the fundamental role of phosphorus (P) in the sea, using Station ALOHA as the open ocean benchmark. While there was a stated emphasis on the element P, the inextricable metabolic and biogeochemical links to C, N, S, O, H and many trace elements implied that the HOE-PhoR mission was a broad, multi-element, trans-disciplinary opportunity that appealed to all C-MORE scientists whether you have a love affair with P, or not. Indeed the use of the term "rally" to describe this 2-cruise expedition was wholly appropriate: to summon or bring together for a common purpose. Scientific collaborations and partnerships, in this case through common sampling and shared experiments to test fundamental hypotheses, was the primary goal of HOE-PhoR. These coordinated activities assessed a range of scales from genes and genomes to populations and ecosystems, and built on the fundamental understanding that has been achieved during the ongoing, 25-year Hawaii Ocean Time-series (HOT) program; indeed the efforts during HOE-PhoR contributed to the year-long HOT silver anniversary and also benefited from ongoing achievements of the successful HOE-DYLAN (2012) project. The expedition acronym, HOE-PhoR, has real meaning and significance: HOE is Hawaiian for get to work, do your share, paddle a canoe, and PhoR is the gene designation for the histidine kinase, the enzyme that initiates the phosphorus starvation inducible response (also known as the Pho regulon) leading to many fundamental genetic and physiological changes in microorganisms.
