Shedding light on processes that control particle export and flux attenuation in the twilight zone of the open ocean

Open access

Abstract

Pelagic food webs drive a flux of >10 x 10 12 kg C yr −1 that exits surface waters, mostly via sinking particles through the ocean's "biological pump." Much of this particle flux is remineralized in the poorly studied waters of the twilight zone, i.e., the layer underlying the euphotic zone and extending to 1000 m. We present a reanalysis of selected upper‐ocean studies of particulate organic carbon (POC) flux and relate these observations to a simple one‐dimensional biological model to shed light on twilight zone processes. The ecosystem model first predicts particle flux from the base of the euphotic zone, and then its attenuation below based on transformations by heterotrophic bacteria and zooplankton, and active downward transport of surface‐derived particles by zooplankton. Observations and simulations both suggest that future sampling strategies for the twilight zone should take regional variability of the euphotic zone depth (Ez) into account. In addition, conventional curvefitting of particle flux data (i.e., power law or exponential) skews our interpretation of twilight zone processes. To overcome these artifacts, we introduce two new terms: the Ez‐ratio (POC flux at Ez relative to net primary production [NPP]) and T 100 (the ratio of POC flux 100 m below Ez to POC flux at Ez). A comparison of NPP, Ez‐ratios, and T 100 provides a new set of metrics to classify the ocean into different regimes, representing high and low surface export and subsurface flux attenuation.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
