In the higher- latitude zones (40°S- 70°S,40°N- 70°N),the sea levels in both the northern - western andsouthern - western Pacific areas are being the obvious risings and their rates in the higher latitude zones are 1. 5 mm/yr and 2. 5 mm/yr, respectively, it is confirmed that the effect ofice - sheet melting in the Antarctica on the sea level change is stronger than that in theGreenland.
This paper describes the method of deriving the annual variability using the data of sea levels at tide gauge stations in China. The annual variability of the sea levels in China derived in this way is 0.14 - 0.20cm/a.
The sea level curves show that under the Holocene transgression sea level experienced many osillations and formed three evident higher (than present) sea levels which occurred in about 6100, 3100,and 1800a,B. P. ago with the altitude less than + 3m, +2m and +1m respectively.
As far as the third order sequences are concerned, seven type Ⅰ and five type Ⅱ sequences, 5.3 Ma of mean duration, are discerned, reflecting the result of twelve third order periodic relative sea level changes, in which Ypresian and Rupelian are respectively the highest stand and the lowest stand sea levels.
Tidal saltmarsh environment controls the features and distribution of saltmarsh foraminifera. According to the study abroad, the vetical zonation of saltmarsh foraminifera can be used as indicators for relocating former sea levels to an accuracy of ±20cm, even ±5cm. This quite high accuracy is important for studying sea level change, environment evolution and global change.
Mean annual sea levels at the Tide-gauge Station of Qingdao exhibit a general rise of relative sea level at a rake of about 1.7mm/year during the past 60 years.
Using the combination of a RSS-111 high pressure ionization chamber and a FD 71 NaI(T1) scintillation radiometer, cosmic-ray ionization was measured on sea levels and lakes with different altitude and latitude.
The tides and tidal currents on the continental shelves of the BYECS at four special periods, i.e., at the sea levels standing at 80m, 52m, and 30m below present respectively, and at the Holocene transgression maximum (HTM), are simulated.
Methods Serum levels of testosterone(T) and estradiol (E2)were determined in 60 elderly men with ACI and 60 healthy elderly men at high altitude (2260 m sea levels above). Serum levels of interleukin(IL)-1, IL-6, tumor necrosis factor(TNF)-α and erythropoietin (EPO) were measured by radioimmunoassay.
This paper presented the assay methods for dissociating erythrocyte lactic dehydrogenase isoenzyme(ELDH-isoenz)activity and zymogram in healthy subjects by polyacrylamide gel electrophoresis and optical density scanning at 7m,2300m and 4300m sea levels.
Methods Four groups from the Qinghai-Tibetau Plateau were collected:40 patients of ACI at 3,400m above sea levels,48 patients of ACI at 2,280m sea levels,70 controls with various high altitudes. Plasma Hcy,Vitamin B12 (VitB12) and folic acid (FA) were assayed by the fluorescence polarization immunoassay (FPTA).
The annual mean sea levels of all permanently recording tide gauge stations along the North American west coast were inspected for evidence of elevation changes before and after large strike-slip earthquakes.
It was found that the present sea level,Z(t) is related to previous sea levels, as well as, present and past values of rainfall,R(t), and temperature,T(t), via a transfer function, which quantifies the relationship.
Tuvalu, approximately 1000 km north of Fiji in the South Pacific Ocean, is one of six countries, all of them island states, that "could face total destruction when sea levels rise….
According to the field investigation along the coastal area of South Fujian and East Guangdong and the 14C age determinations, a number of stratigraphical profiles are described and 14C dates of 22 samples published. The subdivision and correlation of the late Quaternary stratigraphy, the Holocene sea level changes and the characteristics of neotectonic movement are preliminarily discussed in this paper.The late Quaternary stratigraphy in this area can be divided into Jiangtian peat and Jingzhou mud b...
Using the combination of a RSS-111 high pressure ionization chamber and a FD 71 NaI(T1) scintillation radiometer, cosmic-ray ionization was measured on sea levels and lakes with different altitude and latitude. As a result of summing up the measure-ments made during the last three years, a empirical formula is obtained which might be used to estimate the cosmic-ray dose rate in air.The mean value of the measurements of the cosmicrray ionization on the sea levels was 2.93 ±0.07 ×10-3 ...
Based on the 78 14C data of sediments related to the former sea levels, and by means of linear relation, we have calculated the rates of vertical movements of following faulted blocks: (1) the coast of northeastern Fujian Province (including Fuding, Ningde, Luoyuan, and Lianjiang Counties); (2) Fuzhou Basin and Coastal Plain of Changle County; (3) Longtian-Gaoshan Peninsula of Fuqing County and Pingtan Island; (4) Coastal Plain of Putian; (5) Deltaic Plain and estuary of the Jiulongjiang River; ...
