in the Pacific (Coale et al., 1996; Martin et al., 1991) and the Southern Oceans (Bakker et al.,
2001; Boyd et al., 2000; Bozec et al., 2004; Coale et al., 2004) is shown in Table 9.7.
9.3 Microbial Transformations
Microorganisms in the marine environment can be divided into two types: (a) eukaryotes
(10 to 100 μm), which have a complete cell structure and include algae (photosynthetic),
protozoa (predators of bacteria) and fungi, yeast, and molds (nonphotosynthetic); and
(b) prokaryotes (1 to 10 μm), which eat single cells and include bacteria (0.5 to 10 μm),
