  Exploitations 
  of 
  the 
  "Albatross" 
  

  

  manganese 
  nodules 
  were 
  found 
  the 
  hauls 
  were 
  specially 
  poor 
  t 
  

   a 
  few 
  deep-sea 
  holothurians 
  and 
  ophiurans, 
  and 
  some 
  small 
  

   actiniae 
  which 
  had 
  attached 
  themselves 
  to 
  the 
  nodules 
  with 
  a 
  

   few 
  other 
  invertebrates, 
  seemed 
  to 
  be 
  all 
  that 
  lived 
  at 
  these 
  

   great 
  depths, 
  2500 
  to 
  2900 
  fathoms, 
  far 
  away 
  — 
  say 
  from 
  ,700 
  ta 
  

   1000 
  miles 
  — 
  from 
  the 
  nearest 
  land. 
  

  

  The 
  bottom 
  temperatures 
  of 
  the 
  deep 
  (Moser) 
  basin 
  varied 
  

   between 
  34-6° 
  at 
  2628 
  and 
  2740 
  fathoms, 
  to 
  35'2° 
  at 
  2440 
  

   fathoms, 
  and 
  35° 
  at 
  2475 
  fathoms 
  ; 
  about 
  120 
  miles 
  from 
  the 
  

   Marquesas. 
  At 
  station 
  No. 
  23, 
  off 
  the 
  Marquesas, 
  in 
  1802 
  

   fathoms, 
  the 
  temperature 
  was 
  35*5°. 
  

  

  Owing 
  to 
  the 
  failure 
  of 
  our 
  deep-sea 
  thermometers 
  we 
  were 
  

   nO*t 
  able 
  to 
  make 
  any 
  satisfactory 
  serial-temperature 
  observa- 
  

   tions. 
  At 
  station 
  No. 
  11, 
  lat. 
  14° 
  38' 
  K, 
  long. 
  136° 
  44' 
  W., 
  

   we 
  obtained 
  : 
  

  

  79° 
  at 
  surface 
  

  

  78-7° 
  at 
  50 
  fathoms 
  

  

  55-9°

  44-1° 
  "300 
  " 
  

  

  39-9° 
  "

  These 
  temperatures 
  are 
  somewhat 
  higher 
  than 
  those 
  obtained 
  

   by 
  the 
  Challenger 
  in 
  similar 
  latitudes 
  on 
  their 
  line 
  to 
  the 
  west- 
  

   ward 
  of 
  ours 
  between 
  the 
  Sandwich 
  Islands 
  and 
  Tahiti. 
  

  

  The 
  temperatures 
  of 
  the 
  bottom 
  between 
  the 
  Marquesas 
  and 
  

   Paumotus 
  were 
  34'9° 
  at 
  1932 
  fathoms, 
  35° 
  at 
  2456 
  fathoms 
  

   and 
  2451 
  fathoms, 
  and 
  35*1° 
  at 
  2527 
  fathoms. 
  

  

  We 
  did 
  not 
  take 
  any 
  bottom 
  temperatures 
  between 
  the 
  

   Pan 
  mot 
  us 
  and 
  Tahiti. 
  

  

  Our 
  deep-sea 
  nets 
  not 
  having 
  reached 
  San 
  Francisco 
  at 
  the 
  

   time 
  we 
  sailed, 
  we 
  limited 
  our 
  pelagic 
  work 
  to 
  surface 
  hauls, 
  

   of 
  which 
  we 
  generally 
  made 
  one 
  in 
  the 
  morning 
  and 
  one 
  in 
  

   the 
  evening, 
  and 
  whenever 
  practicable 
  some 
  hauls 
  with 
  the 
  

   open 
  tow 
  nets 
  at 
  depths 
  varying 
  between 
  100 
  and 
  350 
  fathoms. 
  

   The 
  results 
  of 
  these 
  hauls 
  were 
  very 
  satisfactory. 
  The 
  collec- 
  

   tion 
  of 
  surface 
  animals 
  is 
  quite 
  extensive, 
  and 
  many 
  interesting 
  

   forms 
  were 
  obtained. 
  As 
  regards 
  the 
  deeper 
  hauls, 
  they 
  only 
  

   confirm 
  what 
  has 
  been 
  my 
  experience 
  on 
  former 
  expeditions, 
  

   that 
  beyond 
  300 
  to 
  350 
  fathoms 
  very 
  little 
  animal 
  life 
  is 
  found, 
  

   and 
  in 
  the 
  belt 
  above 
  300 
  fathoms, 
  the 
  greater 
  number 
  of 
  

   many 
  so-called 
  deep-sea 
  crustaceans 
  and 
  deep-sea 
  fishes 
  were 
  

   obtained. 
  I 
  may 
  mention 
  that 
  we 
  obtained 
  Pelagothuria 
  at 
  

   about 
  100 
  fathoms 
  from 
  the 
  surface. 
  

  

  We 
  trawled 
  at 
  station 
  No. 
  10 
  in 
  3088 
  fathoms. 
  Unfortu- 
  

   nately 
  the 
  trawl 
  was 
  not 
  successful, 
  and 
  we 
  simply 
  hauled 
  the 
  

   bag 
  through 
  over 
  3000 
  fathoms 
  without 
  bringing 
  up 
  a 
  single 
  

   deep-sea 
  animal 
  from 
  intermediate 
  depths 
  which 
  we 
  did 
  not
