NPBY1 - Point Wells: L3 Climatology - Pressure Gridded - 1.00 dbar

The Northwest Environmental Moorings program maintains
a number of buoys thoughout the Puget Sound region, taking regular profiling
casts with a winched CTD attached to a fixed mooring. These profiles measure
water pressure, water temperature, and conductivity. Depending on the mooring
configuration, additional instruments are added to take further measurements,
which can include dissolved oxygen, nitrate concentrations, fluoroescence
(a proxy measurement for chlorophyll concentrations), and turbidity.

This climatology is based upon data taken from casts taken between the years 2010-2024. The data is averaged at each pressure level for each day of a calendar year. After the data is averaged, a 6-week smoothing filter is run over each data level to provide a smoother data record. Climatological averages and standard deviations are provided. When taking the averages, if there is not sufficient data coverage for a given day (i.e., greater than or equal to 80% of the time frame), then no average is taken, and the climatological value for that day at that pressure level is left blank.

description=ORCA Climatology at Pt. Wells: Pressure-gridded
details=This file contains climatological data records for all the sensors at the ORCA buoy at Pt. Wells. Each variable includes a climatological mean and a climatological standard deviation. The climatologies were constructed using data from the years between 2010 and 2023. For more information on how the climatology has been constructed, please refer to the data manual.

西北环境锚泊项目在普吉特湾地区维持着一系列的浮标，定期使用与固定锚泊相连的绞车式CTD进行剖面测量。这些剖面测量包括水压、水温及电导率。根据锚泊配置的不同，还会增加额外的仪器以进行进一步的测量，这可能包括溶解氧、硝酸盐浓度、荧光（作为叶绿素浓度替代指标的测量）以及浑浊度。该气候学数据基于2010年至2024年间采集的剖面数据。数据在每个日历年的每一天的压力水平上进行了平均。数据平均后，对每个数据层运行为期6周的平滑滤波器，以提供更平滑的数据记录。提供了气候学平均值和标准偏差。在计算平均值时，如果对于某一天的数据覆盖不足（即超过80%的时间框架），则不计算平均值，并保留该压力水平下该日的气候学值为空。
