Variation pattern of particulate organic carbon and nitrogen in oceans and inland waters
We examined the relationship between, and variations in, particulate organic carbon (POC) and particulate organic nitrogen (PON) based on previously acquired ocean and inland water data. The latitudinal dependency of POC ∕ PON is significant between 20 and 90° N but weak in low-latitude areas an...

| description | We examined the relationship between, and variations in,
particulate organic carbon (POC) and particulate organic nitrogen (PON) based
on previously acquired ocean and inland water data. The latitudinal
dependency of POC ∕ PON is significant between 20 and 90° N but
weak in low-latitude areas and in the Southern Hemisphere. The mean values of
POC ∕ PON in the Southern Hemisphere and Northern Hemisphere were 7.40 ± 3.83 and 7.80 ± 3.92, respectively. High values of POC ∕ PON
appeared between 80–90 (12.2 ± 7.5) and
70–80° N (9.4 ± 6.4), while relatively low
POC ∕ PON was found from 20 (6.6 ± 2.8) to 40° N (6.7 ± 2.7). The latitudinal variation of POC ∕ PON in the Northern Hemisphere
is much stronger than in the Southern Hemisphere due to the influence of more
terrestrial organic matter. Higher POC and PON could be expected in coastal
waters. POC ∕ PON growth ranged from 6.89 ± 2.38 to 7.59 ± 4.22
in the Northern Hemisphere, with an increasing rate of 0.0024 km from the
coastal to open ocean. Variations of POC ∕ PON in lake water also showed
a similar latitude-variation tendency of POC ∕ PON with ocean water but
were significantly regulated by the lakes' morphology, trophic state and
climate. Small lakes and high-latitude lakes prefer relatively high
POC ∕ PON, and large lakes and low-latitude lakes tend to prefer low
POC ∕ PON. The coupling relationship between POC and PON in oceans is
much stronger than in inland waters. Variations in POC, PON and POC ∕ PON
in inland waters should receive more attention due to the implications of
these values for the global carbon and nitrogen cycles and the indeterminacy
of the relationship between POC and PON. |
