Supplementary Table 1 from Distribution, composition and functions of gelatinous tissues in deep-sea fishes

Specimen information for gelatinous tissue samples tested. N. kermadecensis specimens were collected by free-vehicle trap (described Jamieson et al., 2013). Other specimens were collected by trawl (Drazen et al. 2015). Capture depth in metres. Collection dates noted. Standard length (SL) and Total length (TL) presented in centimetres, mass in grams

Natural stable isotopic signatures of sediments and macrofauna at Station M, (a) δ¹³C in ‰ (b) δ¹⁵N in ‰ and (c) C:N ratios, dotted line represents C∶N ratio of POM flux at 50 m.a.b. and solid line represents C:N ratio of surface sediments.

<p>Data are means (±1 standard deviation) from a series of 8 pushcores. For the sediments and foraminifera black symbols represent surface samples (0–2 cm) and grey symbols represent sub-surface samples (2–5 cm).</p

In plots f and g, dark grey bars represent incorporation from Exp. 1, light grey bars represent incorporation from Exp. 2 and white bars represent mean incorporation of tracer from September. Note the data presented from Exp. 2 in June represents total biomass specific uptake µg C mg⁻¹ or µg N mg⁻¹. Number of replicates in Exp. 1 = 3 and Exp. 2 = 1 and September  = 3.</p

Vertical distribution of: macrofaunal metazoan abundance during (a) June and (b) September; macrofaunal biomass (mg dry weight m⁻²) during (c) June and (d) September; macrofaunal biomass (mg C m⁻²) during (e) June and (f) September; and macrofaunal biomass (mg N m⁻²) during (g) June.

<p>Bars represent means ±1 standard deviation, n = 20 for June and 7 for September.</p

Particulate fluxes at Station M from January to December 2007.

<p>Filled circles and open triangles represent the carbon and nitrogen fluxes respectively. Grey-filled squares represent the C/N ratio of flux material. Solid and dashed lines represent flux material from sediment traps moored 600 m.a.b and 50 m.a.b., respectively. There is no data available from the 50 m.a.b. trap from August to November.</p
