Report on the aquatic chemistry of water bodies in the Vestfold Hills, 1994, John Gibson

This is a scanned copy of the report by the wintering aquatic chemist at Davis Station in the Vestfold Hills, John Gibson.Taken from the introduction of the report:This report covers work undertaken at Davis during the period December 1993-February 1995. It does not attempt to interpret most of the results obtained, rather present the data so that it is available for further analysis. The dataset is not complete - some analyses are yet to be finished.AimThe basic aim of the project was to study carbon flow through three environments in the Davis area. The approach taken was to measure the concentrations and fluxes of as many forms of carbon as possible, as well as many supporting parameters. The sites chosen were:1. Inshore marine - this site at 704905, generally called the O'Gorman Rocks site , was selected so that it would be accessible for nearly the complete year (as compared to sites further offshore, which would have considerable periods of isolation). It also was the site of study by the author during the 1992-93 summer and by others during the 1993 winter. Thus we have three summers' and two winters' continuous data from this site.2. Ellis Fjord - this site was chosen as a model for the marine system, with the advantage that little exchange occurs between the fjord and the ocean. The actual site used was at 833873 - this point was chosen as it was at a deep spot as far from the fjord mouth as possible without being in the Deep Meromictic Basin, where anoxic bottom water could not interfere with the water chemistry. Water depth at the site was circa 73 m.3. Ace Lake - the lake was chosen as it is a marine derived system which is now completely isolated from the ocean. The actual site chosen was near the deep spot in approximately 24 m of water.

本内容取自该报告的引言部分：本报告涵盖了1993年12月至1995年2月期间在戴维斯站开展的相关工作。报告未对多数已获取的结果进行阐释，仅呈现原始数据以供后续分析使用。本数据集尚未完整，部分分析工作仍待完成。
研究目标：本项目的核心目标为探究戴维斯站区域内三种生境中的碳流动过程。研究方法为尽可能测定多种形态碳的浓度与通量，以及诸多配套参数。选定的采样点位如下：
1. 近岸海域点位：该点位坐标为704905，通常被称为奥戈尔曼岩（O'Gorman Rocks）采样点。相较于远海点位（会有较长时间的封冻隔离期），此点位可实现全年绝大多数时段的采样作业。本点位同时为作者1992-1993年夏季以及其他研究者1993年冬季的研究场地。因此该点位已积累了三个夏季与两个冬季的连续观测数据。
2. 埃利斯峡湾（Ellis Fjord）点位：该点位被选为海洋系统的研究模型，其优势在于峡湾与外海之间的水体交换极少。实际采样点位坐标为833873，选址原因是该点位位于远离峡湾口的深水区域，且未处于深层半混合盆地（Deep Meromictic Basin）范围内——该盆地的厌氧底层水会对水体化学性质造成干扰。该点位水深约73米。
3. 艾斯湖（Ace Lake）点位：该湖泊为源自海洋的封闭水体，目前已与外海完全隔绝。实际采样点位选在水深约24米的深水区附近。
