TL;DR: Although the perception that nitrogen plays a major role in the ecology of the sea goes back at least to the turn of the century, it is only in the past 2 decades, after significant advances in analytical methodologies, that the importance of nitrogen to marine primary production and importance of the oceans in the global nitrogen cycle have begun to be quantified as mentioned in this paper.

TL;DR: In this paper, Lignin, elemental, and stable carbon isotope compositions are reported for local plants and for coarse (>63 µm) and fine (<63 mm) suspended particulate materials collected along a 1,950 km reach of the lower Amazon River during four contrasting stages of the 1982-1983 hydrograph.

TL;DR: In this article, the authors presented a new estimate of 450 Tg N 2 O yr -1 (Tg = 10 12 g) for the global ocean, which can be explained only by positing an ocean that has deviated far from a steady state, the need for a major upwards revision of fixed N inputs, particularly nitrogen fixation, or both.

TL;DR: In this article, the authors compare analyses of sediments underlying two regions of the eastern North Pacific Ocean, one which has oxygen-depleted bottom waters and one with typical oxygen distributions.

TL;DR: In this article, the authors made the first inorganic carbon measurements in this estuary on two survey cruises in February and August of 2008, and observed pH and aragonite saturation state values in surface and subsurface waters were substantially lower in parts of Puget Sound than would be expected from anthropogenic carbon dioxide uptake alone.
