I, III, Iv, XxI and xxt, and it gives particulars of observations made by the R.R.S. “Discovery II’ from October 1935 to May 1937. Its arrangement follows that of the Station Lists published in vols. xxr and xxtr. Nutrient salt contents are expressed in milligramme atoms of the particular element per cubic metre of sea water. For pH estimation McClendon’s Standards were used; a correction was made for the fading of the tubes as described in vol. xx1, and the values represent the pH im situ corrected for temperature and salt error but not for pressure. In the estimation of phosphate 2 c.c. of ammonium molybdate were used with a trace of copper and the resulting figures corrected for salt error by multiplying by a factor of 1-35. Silica was measured by the method of Atkins and Cooper and no correction applied for salt error. Depths measured by unprotected thermometers are recorded in the column headed ‘Depth by thermometer’; those recorded in the column headed * Depth (metres)’ were determined from the amount of wire paid out and from the most probable slope of the wire found by interpolation between the thermometric measurements; the small index figure placed above the figure for depth shows from which hoist of water sample bottles the sample was obtained. Time is expressed in the 24-hour system ending with midnight (0000). The difference of the ship’s time from Greenwich mean time (GMT) is noted in the ‘Remarks’ column, this difference holding good until another entry is made. Times in heavy type refer to biological observations made between sunset and sunrise. The following symbols are used for nets, apparatus, etc. : B Oblique. BNR Russell’s bottom tow-net. A 100 cm. net on a frame attached to skids which raise it clear of the bottom. DC Conical dredge. Mouth 16 in. diameter (40-5 cm.) with a canvas bag. DGP Pressure depth gauge: a modification of the Budenberg pattern. DLH Large dredge. Heavy pattern, 4 ft. long (1-2 m.). DRR Rectangular dredge bag bent on to a Russell frame with skids to raise it clear of deep mud on the sea floor in the neighbourhood of the Ross Ice-Barrier. DRS Small rectangular dredge. H Horizontal. KT Kelvin tube. NHP A modification of Harvey’s phytoplankton net. A metal funnel (aperture 30°5 cm.) leads to a recording mechanism and thence to a sleeve-shaped silk net of 200 meshes to the linear inch, terminating in a conical bucket. The apparatus is hauled vertically at approxi- mately ro m. a minute, and the mechanism records the volume of water filtered. - oF Nets with mesh of 4 or 7 mm. (0°16 or 0°28 in.) attached to back of trawl. N 50 50cm. tow-net. Mouth circular, 50cm. diameter (19°5 in.): 200 meshes to the linear inch. 3 INTRODUCTION N 70 7ocm. tow-net. Mouth circular, 70 cm. diameter (27-5 in.): mesh graded, at cod-end 74 to the linear inch. N 100 1m. tow-net. Mouth circular, 1m. diameter (3-3 ft.): mesh graded, at cod-end of stramin with 10-12 meshes to the linear inch. N 450 42 m. tow-net. Mouth circular, 45 m. diameter (14:8 ft.): mesh graded, cod-end of 7 mm. (0-28 in.) netting lined for part of its length with 4 mm. (0-16 in.) netting. OTL Large otter trawl. Head rope 40 ft. long (12-2 m.): mesh at cod-end 1} in. (3-2 cm.). RM Mussel rake. Sh. Coll. Shore collecting. STN Sounding rod. Nansen-Ekman type. TYF Young-fish trawl. A bag of stramin, with 10-12 meshes to the linear inch, attached to a circular frame 2 m. diameter (6:6 ft.). TYF70B Young fish trawl. With 3 or 4 ft. of No. 70 silk sewn round inside immediately above the bucket. Vv Vertical. To the symbols for tow-nets (N 450, N 100, N 70, N 50, TYF and TYF 70) B, H or V is always added to indicate whether the haul was made obliquely, horizontally or vertically. For determining the depths of horizontal and oblique nets, Kelvin tubes or depth gauges were employed. Their use is indicated by symbols in the ‘Remarks’ column, and where no such symbol appears it is to be understood that the depth was estimated. When the depth of termination of an oblique haul is written ‘(—o)’ it must be understood that the net failed to close at some intended intermediate depth and fished all the way to the surface. The last part of the haul from the intended depth of closing to the surface would usually occupy a small fraction of the total time of fishing. Further details of the methods of fishing large nets are given by Marr (1938). For symbols used to denote meteorological observations, see Station List, 1931-33 (Discovery Reports, vol. XX1, p. 3). Soundings taken by the echo-sounding apparatus are marked with an asterisk. At the end of the lists (p. 196) will be found a summary of the stations made by the R.R.S. ‘Discovery II’ from October 1935 to May 1937, with references to the charts on which the station positions are marked.

Its arrangement follows that of the Station Lists published in vols. xx1, xxi and XXIV. Nutrient salt contents are expressed in milligram atoms of the particular element per cubic metre of sea water. For pH estimation McClendon’s standards were used ; a correction was made for the fading of the tubes as described in vol. xx1, and the values represent the pH im situ corrected for temperature and salt error but not for pressure. For the estimation of phosphate 2 ml. of ammonium molybdate were used with a trace of copper and the resulting figures corrected for salt error by multiplying by a factor of 1-35. Silica was estimated by the method of Atkins and Cooper and no correction applied for salt error. Depths measured by unprotected reversing thermometers are recorded in the column headed ‘Depth by thermometer’; those recorded in the column headed ‘Depth (metres)’ were determined from the amount of wire paid out and from the most probable slope of the wire found by interpolation between the thermometric measure- ments; the small index figure placed above the figure for depth shows from which hoist of water sample bottles the sample was obtained. Time is expressed in the 24-hour system ending with midnight (0000). The difference of the ship’s time from Greenwich mean time (GMT) is noted in the ‘Remarks’ column, this difference holding good until another entry is made. Times in heavy type refer to biological observations made between sunset and sunrise. The following symbols are used for nets, apparatus, etc. : B Oblique. BNR Russell’s bottom tow-net. A 1m. net on a rectangular frame attached to skids which raise it clear of the bottom. DC Conical dredge. Mouth 16 in. (40-5 cm.) diameter, with a canvas bag. DGP Pressure depth gauge: a modification of the Budenberg pattern. DLH Large dredge. Heavy pattern, 4 ft. (1-2 m.) long. H Horizontal. KT Kelvin sounding tube. NHP A modification of Harvey’s phytoplankton net. A metal funnel (aperture 30°5 cm.) leads to a recording mechanism and thence to a sleeve-shaped silk net of 200 meshes to the linear inch, terminating in a conical bucket. The apparatus is hauled vertically at approxi- mately 10 m. a minute, and the mechanism records the volume of water filtered. N 50 50cm. silk tow-net. Mouth circular, 50cm. (19:5 in.) diameter: 200 meshes to the linear inch. N 70 7o cm. tow-net. Mouth circular, 70 cm. (27°5 in.) diameter: mesh graded, at cod-end of silk with 74 meshes to the linear inch. N 100 Im. tow-net. Mouth circular, 1 m. (3:3 ft.) diameter: mesh graded, at cod-end of stramin with 10-12 meshes to the linear inch. 198 INTRODUCTION N 450 43m. tow-net. Mouth circular, 4} m. (14:8 ft.) diameter: mesh graded, at cod-end of 7 mm. (0-28 in.) netting lined for part of its length with 4mm. (0-16 in.) netting. NS 50 Experimental high speed tow-net, primarily for krill. Rigid construction of fore and mid sections, which are covered with 1 in. (2-5 cm.) mesh wire netting; after part of cotton netting, with bucket. Mid section has 7 mm. (0-28 in.) netting stitched inside wire; after section of 4mm. (0-16 in.) netting backed with stramin. Width at mouth 30°5 cm. (12 in.) widening to 50cm. (19:5 in.) at } of rigid length and narrowing to 15°25 cm. (6 in.) at end of frame. Length of after part 61 cm. (24 in.) and overall length 198 cm. (6:5 ft.). ‘Towed direct from point on fore end ring and balanced by 28 lb. (12-7 kg.) lead weight secured to frame forward, on opposite side to towing point. OTL Otter trawl. Head rope 4o ft. (12:2 m.) long: mesh at cod-end 1} in. (3-2 cm.). Sh. Coll. Shore collecting. TD Transparency (or Secchi) disk, 50 cm. (19-5 in.) diameter. ADNAR Young-fish trawl. A bag of stramin, with 10-12 meshes to the linear inch, attached to a circular frame 2 m. (6-6 ft.) in diameter. Vv Vertical. To the symbols for tow-nets (N 450, N 100, N 70, N 50 and TYF) B, H or V is always added to indicate whether the haul was made obliquely, horizontally or verti- cally. For determining the depths of horizontal and oblique nets, Kelvin sounding tubes or depth gauges were employed. Their use is indicated by the appropriate symbols in the ‘Remarks’ column; where the tube or gauge failed to register the depth was estimated and is noted as such. Details of fishing large plankton nets are given by Marr (1938). The experimental high speed tow-net (NS 50), when used, was towed immediately prior to a full station. ‘The times of shooting and hauling are thus before the time given for the beginning of the Stations, but the inclusion of this net in the station observations enabled the sample to be given the number of the station con- cerned. The state of the sea is expressed as a number in the Douglas Sea Scale, which is as follows: STATE OF SEA Scale number Description Calm Smooth Slight Moderate Rough Very rough High Very high Precipitous Confused ° Oo ONT AM FW DN The following symbols are used to denote the meteorological observations on the state of the weather: b blue sky whether with clear or hazy atmosphere, or sky not more than one-quarter clouded. be sky between one-quarter and three-quarters clouded. c mainly cloudy (not less than three-quarters covered). d= drizzle or fine rain. e wet air without rain falling. nog INTRODUCTION f fog. fe wet fog. g gloomy. h hail. kq line squall. 1 lightning. m mist. o overcast sky (i.e. the whole sky covered with unbroken cloud). p passing showers. q r squalls. rain. rs_ sleet (i.e. rain and snow together). s snow. t thunder. tl thunderstorm. ugly, threatening sky. v_ unusual visibility. w dew. z dust haze; the turbid atmosphere of dry weather. Soundings taken by the echo-sounding apparatus are marked with an asterisk. At the end of the lists (p. 422) will be found a Summary of the Stations made by the R.R.S. ‘Discovery II’ from October 1937 to May 1939, with references to the Charts (Plates [V-VI) on which the station positions are marked.
