Lưu lượng nước, muối và dinh dưỡng của các cánh đồng muối thủy triều nhiệt đới Dịch bởi AI
Mangroves and Salt Marshes - Tập 1 - Trang 229-238 - 1997
Peter Ridd, Renagi Sam, Suzanne Hollins, Gregg Brunskill
Nghiên cứu về ngân sách nước của một cánh đồng muối thủy triều nhiệt đới ở miền khô nhiệt đới Australia đã được thực hiện, đặc biệt chú trọng vào việc ước lượng lưu lượng nước ngầm. Muối đã được sử dụng như một dấu vết thụ động để xác định một số lưu lượng này. Tích lũy muối trong nước ngầm (hoặc mất mát) là dưới 1 kg/m3/tháng. Nước bề mặt rời khỏi cánh đồng với nồng độ muối cao hơn nước lũ dẫn đế...... hiện toàn bộ

Mangrove Habitat Formation and Response to Holocene Sea-level Changes on Kosrae Island, Micronesia
Mangroves and Salt Marshes - - 1996
Kiyoshi Fujimoto, Toyohiko Miyagi, Takao Kikuchi, Toshio Kawana
Mangrove habitats on Kosrae are divided into three types, i.e., an estuary or delta type, a backmarsh or lagoon type and a coral reef or tidal-flat type. Most of the mangrove forests of Kosrae have been developed during the last 2000 years by accumulating mangrove peat with the gradual sea-level rise of 1 to 2 mm/yr except the landward part of the estuary or delta type. On the other hand, during t...... hiện toàn bộ
The productivity of salt marsh vegetation at Tollesbury, Essex, and Stiffkey, Norfolk, England
Mangroves and Salt Marshes - Tập 1 - Trang 113-126 - 1997
Laurence A. Boorman, Caroline Ashton
This study presents data on the biomass and net aerial primaryproductivity (NAPP) of two contrasting East Anglian salt marshes.One site was at Tollesbury, Essex where the marshes are of theestuarine type and are subject to marsh degradation and erosionwhile the other site was 130 km to the north at Stiffkey, Norfolkwhere the barrier-type marshes are still actively developing withno signs of erosio...... hiện toàn bộ
Introduction:carbon fixation and storage in mangroves and their relevance to the global climate change – a case study in Hinchinbrook Channel in northeastern Australia

Mangrove species zonation and soil redox state, sulphide concentration and salinity in Gazi Bay (Kenya), a preliminary study
Mangroves and Salt Marshes - Tập 3 - Trang 243-249 - 1999
S. Matthijs, J. Tack, D. van Speybroeck, N. Koedam
The relationship between soil redox state, sulphide concentration, salinity and spatial patterns of mangrove species distribution was investigated in the mangrove forest of Gazi Bay (Kenya). Field measurements were conducted to examine the relationship between species distribution along a band transect of 280 m and soil redox potential (Eh) and sulphide patterns, as well as the indirectly related ...... hiện toàn bộ
Factors influencing the variability of Mg, Ca and K in waters of a mangrove creek in Bragança, North Brazil
Mangroves and Salt Marshes - Tập 3 - Trang 9-15 - 1999
M.C.L. Cohen, R.J. Lara, J.F. da F. Ramos, T. Dittmar
Sodium, potassium, magnesium, calcium and physico‐chemical parameters were monitored for one year in a mangrove tidal creek near Bragança, North Brazil, to determine their tidally induced and seasonal variations and the main parameters controlling the concentration of these cations. On a daily basis, cation concentrations showed a strong tidal rhythm due to the mixing of estuarine and mangrove wat...... hiện toàn bộ
Spatial variations of groundwater salinity in a mangrove-salt flat system, Cocoa Creek, Australia
Mangroves and Salt Marshes - Tập 2 - Trang 121-132 - 1998
Renagi Sam, Peter Ridd
In this work the average groundwater salt concentration in a mangrove swamp and tropical salt flat system adjacent to Cocoa Creek near Townsville in North Queensland was measured with ground conductivity probes based on low frequency EMI (Electromagnetic Induction) and V-I (Resistivity) Methods. Transects of conductivity were measured with the conductivity probes and the spatial variations in the ...... hiện toàn bộ
Lateral fluxes of organic carbon in a mangrove forest partly contaminated with sewage wastes
Mangroves and Salt Marshes - - 1999
John F. Machiwa
Lateral fluxes of macrodetritus, particulate matter and dissolved organic carbon were determined. Samples were collected monthly at the mangrove forest–inshore water boundary and within the forest. Floating macrodetritus (mainly mangrove leaves) was collected by a net (2 mm mesh size). Dissolved and particulate matter were separated by filtration (0.45 μm filter) and centrifugation. Dissolved and ...... hiện toàn bộ
A versatile in situ sediment pore water sampler
Mangroves and Salt Marshes - Tập 1 - Trang 73-78 - 1997
Jean-Pierre Carmouze, Valeria Bellotto, John Maddock, Antonio Romanazzi
A simple versatile in situ sampler for extracting pore water fromsediments has been developed, working as a convective samplingdevice (harpoon) or a solute diffusion device (peeper). Used asa harpoon, it avoids modification of vertical gradients of soluteconcentrations, because no suction is applied. Used as a peeper,because of its higher diffusion/volume ratio, its contact timewith the sediment i...... hiện toàn bộ
Extensive shrimp farming, mangrove clearance and marine fisheries in the southern provinces of Vietnam
Mangroves and Salt Marshes - Tập 2 - Trang 159-166 - 1998
G.J. de Graaf, T.T. Xuan
Within the last decade shrimp farming in the Mekong Delta of Vietnam has increased by 3500%. Shrimp farming became un-sustainable in the early 1990's due to the un-planned development of this industry and the resulting self pollution of the farms, the destruction of mangrove forest and the outbreak of viral diseases. Historical data on fisheries, fishing effort and mangrove coverage were obtained ...... hiện toàn bộ
