Ocean observation has evolved tremendously, from collection and exchange of weather and sea state information by ocean going ships in the late 19th century to today’s multisensor, multi-platform, multi-disciplinary, large scale observation networks. Data are now transmitted and disseminated automatically in real-time to a variety of user groups with significant social and economical implications. This paper provides an overview of representative advances in in-situ ocean observation during the past decade. Major driving forces and representative advances and trends in in-situ observation are described. Advances are discussed under the categories of observation infrastructure and major measurement system components including sensor, platform, data collection and telemetry, and power supply. The U.S. National Oceanic and Atmospheric Administration (NOAA) is a major participant of the global ocean observation programs and examples of its contributions and activities are introduced.

Abstract Seepage wells that can convert surface water into groundwater are often constructed near the river valley to obtain more water and lead to smaller drawdown comparing with traditional wells. Seepage wells have been widely used, whilst the groundwater and river level variations caused by seepage wells are still unclear, and numerical models are rarely verified due to the lack of in-situ observation data, which may lead to the results are quite different from the actual conditions. To address those limitations, a large-scale pumping test was carried out near the Yellow River valley in China and a coupled seepage-pipe flow model was established using the exchange yield between the aquifer and pipe as the couple key in this research. The coupled model was evaluated with in-situ measurement. The field observation showed that both the river and groundwater had a positive response to the pumping of the seepage wells. The simulation results indicated that our model can well estimate the pumping rate and drawdown with root-mean-square deviations of 158.235 m3/d and 0.766 m, respectively. Further, it is also found that the groundwater showed the obvious characteristics of three-dimensional flow under the influence of seepage wells and the maximum drawdown should be less than 15 m to ensure exploitation efficiency. These findings provide important information that can guide the design and construction of seepage wells to improve the rational exploitation of groundwater.
