 Methodology:  Smith, C.R., et al., 1996. Phytodetritus at the 
               abyssal seafloor across 10 degrees of latitude in 
               the central equatorial Pacific.  Deep-Sea Research II,

 Notes:
 All samples are extracted from multicores.  Data are displayed as a 
 summary at a nominal geographic location.  The summary consists of 
 samples from one or more cores or stations.  Sample size is 0.5cm.


  Parameter    Description                               Units

  sta_name     station name                              dimensionless
  sta          station number from event log             dimensionless
  lat_n        nominal latitude; negative denotes south  degrees
  lon_n        nominal longitude; negative denotes west  degrees
  tube_num     tube number, multicore                    dimensionless
  depth_core   depth in core, mid-point of interval      centimeters 
               sampled                      
  C14_respir   carbon; as 14C-Carbon dioxide; evolved    micromoles C/meter^2/day
               during incubation 
  C14_incorp   14C incorporated into macromolecules,     micromoles C/meter^2/day
               defined as those insoluble in  
               trichloracetic acid and filterable onto
               a Whatman GF/F filter
  analyt_ctrl  analytical controls placed on the sample  dimensionless
               analysis, defined as follows:   
               pressurized - samples incubated in 
                 chambers at pressures equivalent to the
                 water depth at the collection site
               1_bar - samples incubated at atmospheric
                 pressure 
               poisoned - samples incubated with 
                 formalin, these values represent abiotic 
                 uptake of radioactivity
