TMP_maj_0m_char.jpg (138685 bytes) BCTD SURFACE CHARACTERISTICS

A 3 panel figure of surface (depth < 1surface) 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 20surface) 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.

Profiling PCTD (Downcast)

Monterey Bay time series profiling CTD data (PCTD) and preliminary summary graphs characterizing various samples.

This data consists of shipboard CTD temperature, salinity, dissolved oxygen, and transmissivity from MBARI Monterey Bay time series cruises, 1989 - present, taken aboard the R/V Point Lobos and the R/V Rachel Carson. The data are from the profiling CTD casts. Time series cruises are taken approximately 18 times per year (~3 week interval) at 3 major stations, C1 (coastal), Mooring1 (mid bay), and Mooring2 (outer bay), see map.

CTD casts were made to 200 m with a Sea-Bird 911Plus CTD mounted in a Sea-Bird Carousel Water Sampler, SBE-32, 12-place rosette with Ocean Test Equipment 10-l Niskin bottles (silicon O-rings). Conductivity and temperature sensors are calibrated biannually. The SBE-911Plus samples at 24Hz; data are processed with Sea-Bird software. The transmissometer is a Wetlabs C-star. The oxygen sensor is a Sea-Bird SBE-13 Beckman Module (SBE-13B). Profiling downcasts were binned to 1 m depth intervals.

Depth Contours

Physical (temperature, salinity, dissolved oxygen, and transmissivity) characteristics from 1989 to the present. These graphs were produced by MatLab using triangle based interpolation and a median filter. Please be aware that the scaling may be different for each graph, which may affect comparisons by stations. The x-axis is time in years, the y-axis is sample measurement units. Click on one of the thumbnails below for an enlarged image. Graphs will be updated quarterly (Jan, Apr, Jul, Oct).

PCTD Vertical Profiles by cruise

Vertical profiles per station for 2002 to the present; physical parameters (temperature, salinity, sigma t, transmissivity, conductivity, and oxygen. The blue line is the profile for the station. The yellow error bars are the standard deviation for the climatology for the select station with the black line as the climatologic mean. The climatology is from 1989 to present for stations C1 and Mooring1, while Mooring2 ranges from 1993 to present. CIMT M0 Mooring has been added to the vertical profiles beginning with the July 07, 2004 cruise. Time series cruises are named as such, DDDYY, where DDD is the day of year and YY are the last 2 digits of the year. For examle cruise 00202 is the day of year 002 in the year 2002, similarly 09402 is day of year 094 in the year 2002. The graphs were created in MatLab. The x-axis is the sample measurement unit, the y-axis is depth in meters.
