| Study Title | Diel Metabolites in the North Pacific Subtropical Gyre (KM1513) |
| Study Type | Diel metabolomics |
| Study Summary | Diverse organisms within the marine microbial communities show 24-hour cycles of gene expression, likely driven by the need to harness energy from sunlight and to cope with dramatic fluctuations in solar radiation over the course of the day. Metabolites are the direct product of metabolic activity; they are therefore expected to both reflect and influence the daily cycle of the microbial community. Here we measure the intracellular metabolome of the microbial community of the North Pacific Subtropical Gyre, sampled at 4-hour intervals for 8 days. Concentrations of some metabolites common to many organisms exhibit diel periodicity, revealing synchrony of community-level metabolism. Comparing these data to gene expression data reveals temporal offsets between gene transcription and cellular activity, and ties some metabolites to the activities of specific organisms. For example, the dramatic fluctuations of the disaccharide trehalose likely reflect the daily cycles of {Crocosphaera}, a photosynthesizing cyanobacteria that needs to store energy during the day to fuel nighttime nitrogen-fixation. This study illustrates how pairing multiple types of 'omics and environmental data can provide insight into how the activities of individual organisms lead to community functions such as net primary productivity and nitrogen fixation. |

Collection:
| Collection ID: | CO001425 |
| Collection Summary: | Samples for particulate metabolites were collected from 15 m water depth by niskin bottles attached to a conductivity, temperature, depth array (CTD). Metabolite samples were collected in triplicate at each time point by filtering approximately 3.5 L of seawater onto 47 mm 0.2 micron Omnipore filters using peristaltic pumps, polycarbonate filter holders, and Masterflex PharMed BPT tubing (Cole-Parmer). Filters were frozen in liquid nitrogen immediately after filtration and stored in a -80 C freezer until extraction. |
| Sample Type: | Suspended Marine Particulate Matter |
