Graphs and reports of core properties from shipboard CTD bottle samples taken in Monterey Bay, from 1989-Present. Profiling CTD graphs. Time series cruises occurred at approximately 21 days intervals. From 1989-1992 the cruises occupied 4 stations at which complete sampling was conducted (stations C1, H1, H3, C7), but in 1993 these stations were reduced to 3 along an onshore/offshore transect (stations C1, Mooring1; Mooring2). Major stations consist of C1, C7, H1, H3, Mooring1, and Mooring2. Included in the time series data are the quarterly hydrographic surveys for the stations C1; 67-50,Mooring1, H3; 67-55 and Mooring2. (station map, methods and materials). Chemical and taxonomic updates lag the physical and biological as these parameters are batch processed. Taxonomic updates occur once, at the end of the year while the nutrients are updated quarterly. DEPTH CONTOURS Major Station (composite of 5 stations), Physical and Biological
A 3 panel figure of surface (depth < 10m) characteristics: Anomalies, Daily Averages, and Seasonal Cycle of physical , biological , chemical , and taxonomic properties over a 20+ year period, from 1989 to present. Nitrate profiles were collected only at the Mooring1 site. Characteristics for additional depths (60, 100, 150, and 200m) may be found here. Data were daily averaged, interpolated to 14 day intervals, and smoothed (9 point smoothing for the anomalies and 3 point smoothing for the annual cycle). Anomalies were calculated by subtracting the interpolated value from averaged values for the corresponding 14 day interval. Stations Mooring1, H3, 67-50 have been combined. Stations Mooring, 67-55 have been combined. Major stations are C1, C7, H1, H3, Mooring1, and Mooring2. A 9 point running mean (red line) was added to the Daily Average graph as well as a linear regression (green line); daily averaged values are represented as the blue dots. The slope from the linear regression is per day. Please note the Seasonal Cycle has a 3 point running mean applied. Also shown in this graph is the climatology (black dashed lines) contrasted to the annual mean for the last three years, i.e. 1997, 1998, and 1999 (blue line). These graphs were produced by MatLab. Interpolation is the Stineman
method.
Surface and Integrated Depths: Physical , biological and chemical averages by year . Data have been interpolated to a 14 day interval (Stineman method) and averaged by year and station. Stations Mooring1 (M1), H3, and 67-50 have been combined, as have stations Mooring2 (M2) and 67-55. Updated 08/20/01
