Pacific Ocean adaptation

Figure 3-8 (A) Deviations in 5 C values (%o) for amino acids in HMWDOM from amino acids in sinking POM (5 C-AAhmwdom 5 C-AApom) isolated from several depths in the central North Pacific Ocean (adapted from McCarthy et ah, 2004 only surface POM data from 2°N are used here). Note that we assumed a value of —23.9 for lie not 23.9 (as shown in Table 3.1 of that paper). (B) Depthprofilesof5 CHMWDOM 5l3CpoM for various amino acids.

The sea snake is a marine-adapted serpent belonging to the family of Hydrophi-idae. There are many varieties of sea snakes with different colors, shapes, and sizes. They are well adapted for the marine environment and have a flat tail and a salt gland. Sea snakes are widely distributed in tropical and subtropical waters along the coasts of the Indian and Pacific Oceans. They are not found in the Atlantic Ocean. 

FIGURE 9.52 Mass concentrations of acidic and neutral elutable organics in fine particles ( 2.1 (im) at Hopi Point (Grand Canyon region), at San Nicholas Island in the Pacific Ocean upwind of Los Angeles, in West Los Angeles, and downwind at Rubidoux. The bare represent all of the organics that elute between the n-alkanes C and C , where n is shown under each bar. Note the different scales for concentrations (adapted from Mazurek et al., 1997).

(B) Profile of total DON (North Pacific Ocean at 34 50 N, 123°0 W Loh and Bauer, 2000) and HMWDON (Central Pacific Ocean at 12°S,135 W McCarthy eta/., 1998).

Figure 10.21. Lead profiles in Lake Constance (Summer 1981 data Sigg, 1985) and in the Pacific Ocean (1981 data Schaule and Patterson, 1981). The similar shapes of these profiles, despite the diflPerence in length scales (kilometers for the ocean and hectometers for the lake), illustrate the influence of the atmospheric deposition on the upper layers and the scavenging of Pb(II) by the settling particles.

The gas equilibration method has been used to measure the solubility of various hydrocarbons and halogenated hydrocarbons in varying salinity waters. It is well adapted to measure the C1-C12 volatile hydrocarbons that are considered toxic to marine organisms. It has been used to measure traces of low-molecular-weight hydrocarbons in Cook Inlet waters, the Santa Barbara Channel, and other Pacific Ocean water. It was used to identify and monitor chloroform and other contaminants in New Orleans drinking water. It has been used to monitor effluent streams for halogenated hydrocarbons from manufacturing plants. 

Ocean. During the latest Cretaceous, at 70 Ma (d), Australia separated from East Antarctica, Marie Byrd Land merged into West Anteirctica, and New Zealand moved north into the Pacific Ocean. By the middle Miocene at 15 Ma, Antarctica as we know it had emerged from Gondwana (Adapted from Lawver et al. (1991))... 

Figure 10.12. Biological uptake of Zn and its regulation. (Selection of data adapted from Sunda and Huntsman, 1992.) (a) Specific growth rates of coastal (Thalassiosira weissflogii, ) and oceanic Thalassisira oceanica, /) algal species as functions of log[Zn ] and log[Zn ]. ([Zn J and [Zn J are the concentrations of free Zn ions and inorganic Zn species.) (b) Cellular Zn/C mole ratio as functions of [Zn ] and [Zn J (symbols as in part a), (c) Lines are the same as in part (b). Points represent computed relationships in the nutricline of three stations in the North Pacific these relationships were computed from dissolved Zn versus PO4 concentrations in the respective water columns.
